Hey guy have you seen the PI heads on Seanhylandmotorsports.com? It says they are $359 with valvetrain and cams. This seems like a pretty sweet deal to me. For both heads and a PI intake it would be $999. Would this be about a 40-50 rwhp gain? I was thinking of getting some 17x8 Bullit Chrome wheels, but I may do this instead. What do you guys think?
