did what you are trying to do long ago....
just heads???......be a stretch, unless you're willing to up the compression(waaaaaaaay up).......realistically, you're gonna need heads, cam, exhaust and some gear to achieve your goal with moderate compression.....as well as some good tune....or get some cubes

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.
