Need Opinions I am building a iron 408 for my 2002 Z71 truck with a 234/236, 598/601 on a 114 cam. I have the holley hi ram 102mm intake and a set of twin precision 6765 billet turbos. I am looking at different head combos. What do you think about the warhawk heads? I have found some pretty cheap assembled and good for .700 lift. They have 235cc runners. I am hoping to make around 1200hp on race gas with around 20psi or so.
