B B M HEADS

[bn69stang]

Looks like we are about to take a  field trip to Denver in a couple of weeks to look at the new product , complete and bare . A hands on look at this new head in its stages , kind of excited to have a look at the new fe parts .. Bud

[ScotiaFE]

Looking forward to a report.

[blykins]

I like 'em.  I've had 2 sets in here and they perform quite well, even with tiny valves.

[bn69stang]

Did you get the complete heads , or bare ? did you do any porting at all ? what kind of flow numbers did you get out of them Brent  ?  .. Bud

[cjshaker]

I like 'em.  I've had 2 sets in here and they perform quite well, even with tiny valves.

What? And no pictures or reports on them? Shame on you

So is the stuff publicly available now? Seems first hand info is hard to come by and I haven't seen anything announced that they were available for sale yet except for the one guy who said he bought some parts directly from their warehouse.

I would really love to hear some feedback and see some detailed pictures of the chambers and ports.

[bn69stang]

Doug i have some pics to post when i get home , detail pics of the chamber , intake port , exhaust port and pics with gaskets in place . I have talked to Rob at blue oval in Denver several times in the past couple of weeks and i have ordered a set , they will ready for pick up by mid june and according to Rob they will flow 300 @ .700 lift , and come with a 2.15 intake and a 1.68 exhaust valve size s ..Bud

[bn69stang]

Hey Doug and Forum Members, here are the pics of the Heads
Hope this Helps!

[bn69stang]

Heres the Final Two!

[ScotiaFE]

Those are some good looking holes. 

[bn69stang]

Im ready to try them out on my 428 Howie , Doug at blue oval got 15 pair , im number 4 on the list 2 weeks out and project re-vamp is underway .. Bud

[blykins]

Doug, I posted numbers on the other forum.  I was getting almost 315 cfm out of a tiny 2.08 valve, no bowl work or port work.  Basically just pull them out of the box, do a valve job, blend in seats, etc. 

[R-WEST]

Any idea on cost yet?

[bn69stang]

I  was told by Rob at blue oval  1200.00 bare and  2300.00 as i ordered them , Bud

[CaptCobrajet]

According to my info straight from BBM, the bare head pricing will be $1350 per pair.  At this time, there are no plans to offer a "complete" BBM head FROM BBM.  The plan is to sell the heads bare, and any and all finish work pricing would be decided between the buyer of the heads, and whoever does that finish work.  Some BBM dealers will be folks who can offer the service of taking the bare heads from that point to various stages of finished heads.   

I am doing some testing for BBM now.  I have a pair of the heads here.  I will have info and opinions very soon.  I plan to do some very thorough testing, and will be able to offer my opinion and conservative flow results very soon.  As some may know, if a head flows good here on my bench, it will flow better other places.  I do not know the numbers yet, but I will put my seat work on the heads, with no work further down than 1/2-inch below the seat, and share the results fair and honest, for all to see, on this forum.

  From what I see so far, I like what I am looking at.  As cast and sold, the exhaust throat can accept 1.57 diameter valves if desired for small bore apps, or with an exhaust bowl cut and valvejob they can accept the larger valves.  The intake bowl, as cast, will do well with 2.15 or larger valves.  A person would not want to use an intake valve smaller than 2.15........BUT........the valve placement will compliment the use of a 2.15 diameter, even on very small bores. 

As soon as I have some accurate info I will post it.  Bare BBM heads are available now.

[RobMcQ]

Quick Note: The bare head price IS $1350.00/pr, as was listed in the large post on the FE Forum Classifieds back on April 2nd.
Bud and I were focused on assembled heads during our discussion, and how best to match them to his engine. The bare head
price was just misremembered.
As stated, BBM will only supply bare castings (w/seats, guides & time-serts). Finish work needed on the heads: hone guides, cut valve job, minor blend bottom of valve job cut to bowl, measure chamber cc to determine if it matches customer target (Volume will vary slightly with depth of valve job cut and style of valve head), clean and blueprint assemble.

Good pictures.
I was really interested in the "swirl" chamber in these heads. Technology that's generally only seen on the latest performance heads, and good for keeping a suspended fuel mixture in the chamber and minimizing cylinder washdown. Along with the chamber design they should be happy with some pretty conservative timing. The only drawback I see is that the swirl is aimed at an opposite angle from the port entry, but the numbers Brent got seem to indicate it doesn't hurt flow any. Pretty good numbers for un-ported....if those numbers can be backed up. That intake port roof looks nice. It also looks like there's room for improvement with some gentle contouring around the valve guide and some unshrouding in the chamber for the larger bores.

The port exit on the exhaust looks very nice also. Although that would almost be detrimental in a shock towered car because of the tight bend needed on the header tube. Should work very well in a non-towered car. It will be interesting to compare the exhaust to the raised port BT head.

[bn69stang]

Sorry Rob my bad , i guess i was paying more attention to the finished product , thanks again ..talk to you soon ..Bud

[Ford428CJ]

I cant wait to see what Blair has to say about these heads and what he finds. Good to see what the conclusion is on everyone's part!

[bn69stang]

A block is on my list in a year or so , when i recover from this years buying spree lol , hopefully Rob has one to look at when i pick up my heads in a couple of weeks .. An all aluminum 482 would be cool http://fepower.net/simplemachinesforum/Smileys/default/cool.gif

[e philpott]

any new flow numbers yet with 2.15 intakes ??..... Brent , Blair or anybody ??

[BH107]

Rob posted these numbers on the other forum.

"For reference, I pulled some flow numbers from a BBM head we did last week. Standard set up with 2.150/1.680 valves, our valve job with very minor blend on the bottom edge of the seats to bowls, SF600 bench, machined plate entry radius and with & without 2" exhaust pipe.

[bn69stang]

Yes it will be interesting to see what Blair thinks , and what results he gets , and his porting opinion of the new heads .. Bud

[Joe-JDC]

I just completed a valve job on a set with 2.080" intake valve, and 1.600" exhaust valve on Serdi valve machine.  Honing the guides took nearly two hours because of the hardness of the guide material.  My machine operator said it was the hardest guides that he had ever tried to ream/hone.  I had the typical multi-angle intake seat, and back cut the intake valve and a custom exhaust curved seat with 45* exhaust valve face.  Here are the flow numbers for these heads.

Intake
.100      63.98
.200     136.09
.300     207.18

This was on my Super Flow 600 # 6729 @ 28", 70* 38% humidity in airconditioned room and with a calibration test done on machine.  I will be cuting the seats for larger valves and retesting and I will report as I get this done.  Ultimately I hope test with 2.190/1.710 valves, and fully hand ported.  Joe-JDC

[ScotiaFE]

Hey Joe
Would these intakes be stockish Cobra Jet type with the 30* seat?
Really looking forward to some more of the test data of the bigger stuff.
You know pretty much any voodoo stuff your willing to release. 
Thanks for the effort.

[Joe-JDC]

Serdi mullti-angle with 45* seats on both valves.  I was surprised at the turbulence at low lifts from the seats being proud in the ports, and it will take a rather large valve to cut the throats out that far to get rid of the protrusions in the airstream.  Maybe just my heads, but still most folks who buy these will probably want bigger valves anyway.  Joe-JDC

[cjshaker]

Even BBM seemed to suggest that these heads were more suited for the 2.190/1.710 valves. Even mentioning up to 2.25 intakes, so the throats and bowls must be designed to support that? It will be really interesting to see how they progress with the larger valves and port work.

And I 2nd what Howie said, thanks for your effort and posting it, Joe.

[bn69stang]

Thank you Joe for posting , and keep us posted on bigger valves and any porting .. Bud

[RobMcQ]

Actually, 90% of our development and testing was done with the 2.150" / 1.660" and later, the 1.680" valves. The bowls, throats, and chambers were all designed to match to the 2.15/1.68 valves. (The seats will handle the larger 2.250/1.750 size valves, but the bowls, throats, etc. will have to be opened up to complement them.)  We used 45* seat cuts during all of our development work.  The I.D. of the seats were left small on purpose, and will "hang out into the port" with smaller valves - like 2.09"/1.60", requiring some blend work.

Our goal was to have the as cast port/throat match up very closely to the valve seat when cut for the 2.150/1.680 valves, using the special seat cutters we developed for these heads. Due to typical machining variables, the factory didn't get the seat inserts perfectly matched up to the throats, but they are very close and will only need some minor blending, once the valve job has been cut. The throat/valve percentage numbers fall into place, and the ports flow VERY cleanly without turbulence.

It makes sense to the average guy explained that way , the Edelbrock even performs better with bigger valves , maybe one of fords better ideas was nt to use 2.09 / 1.66 with a 3/8 stem and a 30 degree seat , but its 40 plus year old technology . Either way im looking forward to my set of BBM heads .. Bud

[CaptCobrajet]

I've got some flow numbers on the BBM head.  I did what I'd call a ".600 lift" valve job on the head.  I figure a guy with more cam than that is going to port the head anyway.  I try to do whatever I do to a head with the end-use on my mind.  I approached this test with a street to street/strip flat tappet or hydraulic roller on my mind, with a max of .600 to .650 lift and a minimum of .500 lift.  I measured the throats, and a 2.15/1.600 combo will clean up in the bowls with a reasonable throat percentage.  I had some nice 2.20/1.65 stuff here on the shelf, so I did my work with the latter.  I sized all of the guides in the head while I was at it, and it took about fifteen minutes to get within .0002 of where I was going.  It will take another 15-20 minutes to get them to finish size.  They worked like everyone else's guides that I do the same work to.  Carbide is a wonderful thing on manganese bronze.  I did the valvejob, and I left the throat fairly small for a 2.20 valve..........just enough to kiss the aluminium under the seat ring.  No grinding in the bowls at all.  I did blend slightly on the short side.........again just enough to remove any mismatch as the short turn breaks over..........say from about 4:30 to 7:30 of the circle, just on the short turn side, right at the bottom of the seat ring.  Nothing was done on the exhaust underneath the valvejob, except a touch with a 80 grit roll just to knock the machined edge off at the bottom of the seat ring, on the short side.  I did a slight blend right at the spark plug on the top side of the intake seat.  It took nine minutes to do the extent of the "touch up" on one cylinder.

I flowed on a 4.200 bore plate.  Looking underneath, the chamber will not be unhappy on smaller bores.  There was a noticeable "ledge" so I'm sure a stock 390 bore would be just fine with the as-cast chamber.  The valve spacing also allowed the 2.20 valve plenty of room on the cylinder wall side of the chamber.......I don't see any problem using the 2.20/1.65 combo on a 390 bore.

[Barry_R]

To simplify things a bit
I tweaked the layout & rounded the numbers to make them comparable - but have not materially altered any of them.

I will leave comparison to my heads up to you guys - the data is out there.

[cjshaker]

Very good informational posting by all you guys. Thanks for all your efforts.

Obviously they respond pretty well to bigger valves with little to no work, especially those exhausts! Blair is past the 70% rule with barely a light touch-up. And Joes numbers show they would be easily useable in about any mild street build with just basic valve jobs. Should get really interesting as things get opened up to see their full potential. Great stuff.

[CaptCobrajet]

I was using some pretty spiffy valves also.  The exhaust valve is a combo I have been tweaking for a long time.  Valve shape can make a huge diff in the middle of the range on the exhaust side, but that is one nice exhaust port for an as-cast part.

[bn69stang]

Great feed back Blair , Joe , Brent , Barry i know i appreciate all your efforts , as do the all the others and Rob McQ thanks for the phone calls and emails and info on the heads . Ready for a road trip to Denver ... Bud

[blykins]

Joe, did you do any seat blending with the small valves or did you just do a valve job and flow them as-is?   I used a set of Manley valves on the head that I posted the numbers for.  I also used a 50° angle on my set, which explains the better flow up top and the worse flow at lower lift numbers.   These were very quiet on the bench.

For giggles, this is how the head looks on a standard bore 352 block with a 2.09/1.6 pair:

[Joe-JDC]

No, I did not blend the throat, I wanted to simulate a typical multi-angle valve job from any machine shop, and find the results for a specific valve size.  I will go up in sizes, and blend the throat at the size used by BBM and Blair, to see if the heads will be repeatable by different shops.  Personal attention to detail will always increase the flow when done properly, I was just keeping the heads as received from a typical shop for testing.  When I get to the final size for valves, I will flow the heads, and then port them and re-flow to see what difference the porting will make.  I suspect they should respond well, but whatever I get, I will post.  Joe-JDC

[ScotiaFE]

Well I got my set now.
They come really well packed in one box.
First thing I noticed is they are drilled and tapped on both ends.
This will be a great thing for mounting with front engine mounts.

[bn69stang]

Ok forum members i am heading to Denver to Rob s shop , blue oval performance to pick up my heads , and i will post flow numbers , and any other info when i return home . Looking forward to meeting Rob , see ng his shop and projects .. Bud

[sumfoo1]

So we'd want blair's exhaust and brett's intake?

lol


Barry aren't your numbers quoted without any port work too ?

[Barry_R]

I have posted flow data in a couple places with normal valve job & blend.  For third party comparisons Joe Craine has posted flow numbers on my heads with basic valve job, with different valves, and with a couple levels of port work on a couple forums as well.

[Ford428CJ]

Very nice numbers. Heads with the valves that made those numbers would cost me how much?  Valve weights? Options? Not Shipping or anything. Just trying to get a handle on how much I will need to spend building myself a FE. My garage and basement are empty so you can see where I am coming from I will need everything.

[e philpott]

needless to say but it looks like we (FE'ers) have some good or better options on cylinder heads than  the normal Ebroc/BT heads from before ..... looks like you can't go wrong with BBM or Survival head ..... I know I never wanted to deal with header relocation of the BT heads in my shock tower car and the Pro Ports are just a little out of reach , even on my tippy toes just can't get there , I need a shorter money tree with more money on it

[SE2839]

Congrats bn69stang on the excellent numbers on your new heads, Rob seems to be an excellent guy to work with. I hope that mine which should be completed in the next week or so will flow as nicely too. The valve springs on my current C6AE-R heads valve float begining at around 5800 so the stiffer springs and tool steel retainers should also provide added benefit along with the improved flow and better heart shaped combustion chambers and milled for 71ccs. Looking forwards to the installed SOP experience, hoping to see around a +/-70 HP gain it's too bad that I will not have them installed before the Meltdown Drags in Byron Il next weekend.

[bn69stang]

Thanks  SE2839 , im looking forward to the change as well , i went with tool steel retainers and hyd roller and a bigger carb and i am eager to feel the difference , should be about 75 hp range as well .. Bud

Ed,

Is your engine going back on the dyno before you install it? It would be nice to see back to back numbers from your current build to the BBM heads. If I remember correctly your C6AE-R heads were prepped to be similar to out of the box Ed heads right? If your HP predictions are right that should put you around 530 hp?

[bn69stang]

I too plan on putting mine on the dyno , i did nt dyno the first time around and about all i have to go off is Jay s book so , and i have decided not to change the rear gear until drive the car , and not change everything at once  so heads and cam , then carb , then rear gear ?  ? .. sorry im not Ed   but wanted to add my 2 cents   lol   Bud

[SE2839]

I have thought about putting it on a chassis dyno for some before and after results but I have not made that decision as of yet. There is a chassis dyno about 50 miles from me but I do not know of any engine dyno's in this area and I have not decided whether to pull the engine to work off of a stand or bust my knuckles within the confines of the fenders. The C6AE-R heads had just some very mild porting and bowl blending done, they were never flow tested but I have a friend (locally) with a flow bench and so do plan to flow both on his bench just to compare those numbers and since I will have Rob's data I can compensate the data for the iron removed.

I have based my expectations upon a build similar to my own that Barry had done for a gentleman named Patrick in Germany. That engine had the same bottom end (445 stroke crank, rods, pistons and cam) but with prepped Edelbrock heads and a Victor intake. I do not recall the carb but in any event it had dynoed at 531 horse power  Barry had posted the results along with the accompanying video. I actually feel based upon Jay's testing in TGIC that with my dual quad intake and carbs I should have slightly more power with the heads being even but I also expect that the BBM heads will marginally outperform the ported Eds as well and so I'm hoping that I will actually see closer to 540. To be certain it is all just bench racing a this point though. 

[bn69stang]

Ed  what are the specs on your cam ? , have you try d a bigger carb .. Bud

[bn69stang]

Oops my bad i see your you have 2  4s ... need glasses  lol   Bud

[SE2839]

The cam is a Comp custom ground for Barry- 287/293 Advertised, 236/240 @.050, .594/.598 Lift, 112° Lobe Separation/ 104° Intake Centerline.

The carbs are Barry's QFT 750's for the FE. Never needed any more carb than that but I suppose I could play with the jetting or the secondary springs if it were ever warrated. have to see what the new heads make it do.

The C6AE-Rs were the original heads from the Comet, the rest of the original motor had been rebuilt and is wrapped in plastic the car will never go back to stock at this point so I have been kicking around the idea of marrying it all back together in the same configuration as was originally laid out in the Comet which started me on this path of insanity and dropping it into a '63 Fairlane I picked up around 2007 that has been stored for almost 30 years and is just taking up space.

[Barry_R]

I seem to remember that when the engine was built the plan was to go to the track a couple times each year just to see what it would run...  What is the best ET so far?

[SE2839]

That is still the plan, I will be hitting the track for the second time this year at this weekends Meltdown Drags in Byron Il and may make one more go before the end of the season. I had done a bunch of suspension work to the rear to improve traction, added a Gear Vendor unit and had changed gearing this spring (I have the parts for the front end but have not put them on yet). When I went to the track I had my kick down linkage adjusted too tight and had to let out for shift from 1st to 2nd and again to 3rd managing an 8.3 in the 1/8 with a 1.6 60'. I expect to do much better this weekend with not having to let off till I have crossed the end.

[SE2839]

Bud, How are you coming along with your upgrades? Which cam did you end up with? Got a dyno session planned? Looking forward to hearing how the heads are working out as your build comes together. Ed

[bn69stang]

Hey Ed i am still a few parts out on starting this re vamp , i want to have all the parts i need before i take it apart . The cam is a custom comp  232-240 @ .50  .559/.563 on a 112 lobe . This motor has been together for about 3500 miles maybe , stock out of the box Eds and a small hydraulic cam 228-235 @ 50 .538 on a 112 lobe . I am also going to a TKO 600 from a 500 , going to 3.89 from 3.50 s , and going to put my holley hp 850 on as well . I plan on putting it on the dyno , i am looking forward to a seat of the pants difference and would really like to see a solid 70 to 75 hp gain .. The first edition of this motor was nt dyno d , but after reading Jay s , Barry s books i wanted to change some things , to get 500 hp out of 435 inchs is only 1.15 hp per inch , 520 is 1.19 it should be doable somewhere in that range im thinking .. Bud

[SE2839]

Bud, that is a lot of change to take place and you certainly should see some dramatic change occur. That said my head swap may provide the more comparable (for now) before and after results though it will likely not include dyno data the time slips should give some useful information save for track conditions and air quality differences. Perhaps another book by Jay to accompany TGIC will be in order comparing heads used on the same standard and stroker mules. Maybe even a box set to include volumes on cam  selections and blocks as well as another has already suggested.

Yeah Ed i agree with you , I could have went bigger on the cam i guess .. next motor  lol  and i would love run 2- 4 bbls  , but i love the way the shaker scoop looks . I think most of all i am looking forward to the tranny change - the tko 500 had to deep a 1st gear , even with 3.50s and 2nd thru 4th needed more gear to me , and 5th was only good if you were going  90-100 mph . I have sure spent some money this summer .. Bud

[SE2839]

I hear you on the money aspect. I keep lying to myself saying that this next big item will be the last, front and rear suspension was this years project and the gear vendor and heads were on the docket for next year but I got impatient. lol

[bn69stang]

Yeah i got real impatient this year , lol   oh well it s only money rite .. i will get it together and be happy , for a while and save , and save , and did i say save  for an aluminum 427 block ..... Bud

[bn69stang]

And as far the BBM blocks , in both aluminum and cast iron i saw them both and the castings looked great , iron is available now and the aluminum block by sept or oct this year , i would love to have an all aluminum 482 - 500 cubes in my 69 mach .. Bud

[SE2839]

That would be my next engine too, an all aluminium 4.375 stroker with aluminum rods and all the best internals. Or at least it would be if money were no object.
I talked to Rob earlier today and he said that my heads are shipping tomorrow. He said that they flowed 305/213 (225 with pipe) at .600 which made my day, I cannot wait to get them in the car and feel the difference.

What intakes match up to these heads ?

I know some heads flow awesome but require tons of work to mount up to any readily available  intake manifold. (edelbrock etc.)

I know the blue thunder heads and pond heads require some serious work to get the ebrock intakes to fit right.  I'm not sure about barry's heads or these ones.

I know my mint Ford Tunnel Wedge and a NIB Edelbrock RPM line up pretty good on a Genesis and a perfect 105 block.
Just placing them on doing dry fits.

[bn69stang]

BBM is working on a tunnel wedge intake as well , in design now .. Bud

[SE2839]

any of the factory intakes and better aftermarket intakes should correctly fit the Edelbrock's, BBM or Survival heads without issue, some cleanup at the flange may be desired at most. The Edelbrock Pro Ports are a different story the ports when completed are moved considerably requiring either custom or well worked intakes and I believe the exhaust is also a concern.

While I await delivery of my heads from Fed-Ex the delivery of the flow results to my email was much faster serving to increase my anticipation of their arrival and installation. That said here are the numbers flowed at a mile high.

Congrats  Ed , nice flow numbers and keep us posted on the change , as i get ready to start mine .. Bud

[SE2839]

Thanks Bud, Heads arrived yesterday. Packaged well and look to be excellent in quality and workmanship. Really impressed, valves look huge, I cannot wait to see how it wakes it up. I will post pics as it goes together and provide the data as I collect it.

[bn69stang]

Good deal Ed keep me posted ,  bn69stang@gmail and  ( 505 ) 934-4127 if you get a chance call or e mail me . I have a few questions and also to share info .. thanks   Bud

I don't know if this will bump up to the top, but I have a follow up of a sorts on my BBM heads.  I started working on them with the 2.080/1.600 valves, and I could not get over 312/200cfm no matter what I did to the ports.  The exhaust simply would not pick up flow, only 210 with a pipe.  That frustrated me to say the least, so I ordered another set of heads, and they came yesterday.  The seats and ports are completely different from my first set of heads.  The seats are flush with the combustion chambers, and there are no voids under the seats where the seat is standing proud in the ports.  SOOO...hopefully these should flow differently than my first set.  It always amazes me when I hear of flow numbers that I cannot come close to duplicating on my flow bench.  I have been at this for over 40 years, and when I cannot equal someone else's flow numbers, I start looking for the problem in my work.  It is not my work, it is these first set of heads are just different from the second set.  I feel confident I can figure out the exhaust ports' shortcoming on the first set.  We shall see.  Joe-JDC

[cjshaker]

Joe, why we're those heads different? Did you get a pre-release version? Just curious because nobody has mentioned anything about different versions. I wonder if they're all the same now?

[Joe-JDC]

Received a call from Doug at BBM, and he says they are all from the same lot#.  I have taken a few pictures of the combustion chambers and sent them to Doug.   I do feel there is a difference in the installed height of the seats from the first set of heads, and I would post pictures if I were more computer literate.  I just enrolled in Photobucket, so hopefully I can begin to download a few pictures all along of different projects dealing with FE's.  I haven't posted pictures since the origional FE forum, so it will take me a few attempts to get back in the know how.   The new heads look good, I just need to get aggressive on those valve jobs and maybe things will turn around quickly in the flow department.   Joe-JDC.

[ScotiaFE]

Here is a couple of pictures I took of a BBM chamber.
The seats do stand proud in some spots and deep in other spots.
The heads have serial numbers engraved on them.
Still the best looking FE heads I have.

[427HISS]

Any updates ?

[bn69stang]

Updates as to which part of the topic ? ,, Bud

[427HISS]

Well, they haven't been very active on their website. Was interested in their prices and any updates to products.

[blykins]

Why don't you just call, or read the same thread that you posted on Club Cobra, where the guy answered your questions on the pricing?

I googled "club cobra" and got a few hits.
Is this where you guys normally hang out?

Why as a matter of fact.
At anchor just north of Haiti, tiny island called Inagua.....  we have been here for months and have dubbed it "Prison in Paradise"

[Stangman]

Dont mean to change the subject but the guys at work have been talking about Korea,
which made me think about were the foundry for BBM heads and blocks are made south or North
Korea. Just wondering if anybody knew.

[Royce]

South....

[funsummer]

South Korea quiet a nice place, Giant ship yards, Samsung heavy industries and daewoo.
Was up there last year, nice beer.

[Stangman]

Thats a plus
