Pontiac put 72cc no.48 heads on a 350P to make the 350 HO- other than the smaller opening for the 326 and 350, I don't see what else would be needed for that head gasket. It's also a Corteco gasket, so as long as everything is clean and flat it should seal very well.

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.
