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

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.

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

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

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.

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.
