what can i do to wake up my 454. so far i have an exhaust system, headers, TBI chip, kasper throttle reposition sensor, cold air intake, modded the FPR for 14 psi of fuel, and a throttle body spacer. im thinking of getting a set of vortec heads? will they fit on my 91 454? what sort of power gains can i expect from those heads?
