You will need dished pistons for pump gas. They need to be converted to screw in stud and large valve would be good idea. Also on mine the end exhaust port had to be drilled and tapped for the header bolt. They are a good core to prep for HP use.

I've got a set here, they measured 75cc's. We opened them up for 2.11/1.77 valves and heli-coiled them for screw in studs. On a 455 the CR would be over 11 to 1. They make really nice street heads for the 400 engines, ours are for sale if anyone is looking for a ready to bolt on set of heads?....Cliff

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
