when in doubt;
Use a gasket that matches your heads.

Again, 1972 and later intake gaskets will fit any heads IF a 1972 and later intake is used.
A 1971 or earlier intake WILL leak exhaust on passenger side on 1972 or later heads unless special measures are taken to cover/eliminate the blind hole above the crossover channel on the passenger side. |

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.
