Hello guys recently my engine in my 04 m6 gto seized on me. I only had a cam in the engine (g5x3) on stock 241's with dual valve springs, comp roller lifters, and chromoley pushrods I put down 329RW after tune, which wasn't bad to me for the beginning of my build. Today I found the bottom end of lq4 motor. In which I would put my G5x3 cam in the lq4 I was wondering which heads would be best to run to gain the most power, for that cam (RW&Torque). I will also run ls6 intake manifold on this don't really have funds for FAST intake, I am looking to get 400 RW. I also have brand new LT pacesetter headers that will go on the lq4 build. Again my question is which heads and other mods will get me 400RW on this motor? thanks in advance
