FI heads advice needed I have a 370 with heads cut .035, f1a Procharged combo making 937/842 right now. The tuner had to stop adding timing as the heads were starting to lift pushing a little water. The motor has to come out for other reasons so I was going to take the opportunity to to put a set of thicker deck aftermarket heads on while it's out so it can make the power it should. I just don't know which ones to go with. I've done a good bit of research already and am leaning towards Texas speeds prc 260 ls3 heads. They have a 3/4" deck surface unlike the trick flows which I believe have a 5/8" surface.
I know I need to be at a 64cc chamber so I can keep my compression where it is now around 10.6:1 and I want to stay square port also. Someone point me in the right direction.

I went w/ the Mast Med Port LS3's. We cc'd the heads & the numbers were a little off from Mast's advertised numbers, but they still flowed excellent on the bench. I'm not home at the moment or I could get you the numbers.
