The x heads are nice. I had them on a 331 stroker and they flowed very well. Just do a little clean up on the bowls before installing and o-ring them.

what he said, X heads do well all motor i had friend of mine with 347 with X heads went 11.2's on motor with TKO 5-speed i wanna say it dyno'd high 300's on motor it was good running combo but a little driver error consistantly on the 2-3 shift i think probably a good 11.0's on motor, what bottom end are you using? is it a forge piston short block??? i seen a stock short block with the TFS head intake and and stage 1 cam combo on stock bottom end go a 10.60 before with 460RWHP tuned by scott that owned prospeed i think now he's at modular powerhouseOriginally Posted by crashtke
Scott owns Coupe Performance in Porterdale and is very well known for porting heads and dyno tuning, don't even know if he knows' Tim @ MPH. Jeff owns ProSpeed with a dyno while doing excellent work but does not port heads and is combining with Tim @ MPH as we speak.Originally Posted by PUNISHER
I have a stock bottom end 302 B cam with Edelbrock heads runs a 12.0 through an auto and a 10.40 on a 150 shot.
I also have a Trick Flow headed 306 car that weighs less through an auto runs 12.10's on motor with a stage ll cam and way more engine. Add the bottle and it just does get in the high 10's.
Then I have a full interior coupe with nothing gutted (full weight with heat, stereo, Etc.) junkyard 302 motor with an E cam and Edelbrock heads out of the box running low 12's no juice what so ever.
The TFS are ok but I don't like to be limited on choices so I would recommend the Edelbrock's over everything suggested except maybe some AFR 185's if you have enough motor.
No offense to anyone but I wouldn't run any of the Gt-40 heads unless they are free or close to it. Go ahead and save for what you want instead of settling for something that you won't be happy with.
There is a set of Gt 40's on SCF for $300 that is well worth it if your interested.
