I just purchased a 1975 pontiac 455, compression ratio 8:1 and 210 hp. If I put on 1972 7J2 heads, combustion chambers are 96cc, 1.96 and 1.77 valves, will I feel a noticeable difference? Will this combination even be feasible? Thanks for the help guys.

To answer both of your questions:
No and No. The heads you have on that 455 are already better than the 7J2's, using the 7J2 to get a smaller chamber to raise compression would be a poor choice in head on a 455.

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.
