Pull all galley plugs, have them tap & thread the front two openings behind the timing chain for shallow pipe plugs. They will need to “fit” the cam to make sure it rotates well after the cam bearings are installed. Assuming this is a shop knowledgeable with Pontiac engines?

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.
