I Have A 2002 Lq4. Going To Buid It For My 70 Nova Drag Car. I'm Looking For Forged Pistions For 12.5 To 13.1 Compression. I Cant Find Any. I'm New To The Ls Style Motors So I Dont Know Whats Out There Yet. Also Looking For A Cam For Drag Racing. Thinking About Some L92 Heads, Or Ls6 Heads. Carbereted Set Up. Looking For About 550hp Or More. Going To Spray It 150 Shot Too. I Have A Rossler Th400 With Brake And A Strange Axles S60 With Spool 4.10 Gears. Need Some Input.

Its been a while since I looked at the differences between heads but off the top of my head a true LS6 has more compression from smaller chambers and different valves but the ports them selves are very similar.

I would clean up the heads you have and maybe mill them, change cam, full length headers, and with the carb intake you should have no problem getting over 500 hp.

I have been told you can use a EFI cam the only difference being is that they have a narrower lobe seperation. It just depends on your combo and what your doing with it. Most of the big name companies have alot of valvetrain parts.
