New Trick Flow FE cylinder heads & Intake

[sumfoo1]

I'm as interested in that comp rocker setup. But I can't find it anywhere.

Used to be t&d or bust on an engine with this kind of power lift etc.

Both Jegs and Summit have the Comp rocker arms:  http://www.jegs.com/i/COMP-Cams/249/19046/10002/-1

The Comp setup does nothing to insure you won't pull a rocker stand stud out.   Power and lift doesn't necessitate the rocker arm system.   Spring pressure and rpm will be the biggest deciding factors. 

As a matter of fact, the T&D street rockers won't insure that you won't pull a stud out either.  The T&D race setup is your only bet against higher spring pressures.

Just got info on the latest build at my local shop.   464ci 428 with TF heads, .630 hyd roller(246 @ 50), 11:1 pump gas with I think a Victor Jr, tri Y headers.  610 hp at 6200, 580 ft/lb at 4500.  Nice streetcar motor.

Compared to:
My 462ci, .63 flat tappet, 12.5:1, tunnel wedge, 625 hp at 6500, 590 ft lb at 4000 rpm with 20 yr old Eds with hand port job that flows 280/220(same as Barry's heads).

Nice build.  It compares pretty well with the better BBM/Survival builds done with bowl blended heads, pretty much as expected. 

If the Tri-Ys are normal 1 3/4" size, suspect it would pick up a bit with more primary, maybe 10-15hp SWAG.

Ya, they thing a bigger tube would help.  They'd like to try it with a tunnelwedge too.  I get the run around every weekend when I stop in and they want me to put a set on the wagon motor.  Cha-ching......along with a roller cam!  I like my dump truck motor just the way it is.

Yeah, not sure spending $3200 - 3500 or so between heads, lifters, pushrods, cam....and maybe going .2sec faster if you're lucky makes much sense

Was there any mention of having to use the very thin Cometic intake gaskets? Using a 0.020" intake gasket would be a little disconcerting to me.

Lucky for me I never fell in that hole of "I have to go FASTER FASTER!!"

Alan, I have to ask about the head gasket.  Don't really know.  Last weekend they were going to dyno it but had two lifters that would not pump up.   They had the intake off and waiting on replacement lifters.  Got a text the other evening that they made pulls and was given the results.

I'm not sure this HR article on the new TFS heads was posted here. Oh, well, if so here it is again......

That is a nice article!

Any updates on these heads as of late?  I have a set bolted to my Survival built 445 short block that will hopefully be going on the dyno in the next couple weeks.  Waiting on the machine shop to mill my intake. These shops can’t ever seem to get you your parts quick enough.

You are the second person I have read about that has had to have their intake milled or use very thin intake gaskets to get their intake to fit properly. I wonder if this is a common theme with these heads. I have a set that I haven't bolted on yet. I will probably try a couple of different intakes but I don't want to have them milled to fit the heads. I guess time will tell.

Yeah, I think it’s a sure bet to need to mill the intake. I have a Edlebrock rpm intake and have to mill it .045”.  With out the mill, I would have needed a .020 gasket which would never last on a street motor.  The guy that built that 700hp motor went with the .020” gasket. I did have the Edelbrock rpm heads bolted on at first and my intake fit perfectly, but I found that I needed to shim my valve train up .030”!!  I wasn’t cool with that, so head swap it was.  Choose your poison I suppose.  I am using the new comp cans gold rocker setup btw.

Alan, it's not the heads.  It's a fairly common theme to have to cut the intake with any heads or setup.  I have to cut the flanges on about 75% of the FE's I build.
