The machine shop used 30677 Durabond Valve Seats for the exhaust on my '716' heads.
Exhaust valves - 6001SG S.I. Stainless - 1.660" x 4.970". We used readily available 1.96" and 1.66" stainless valves with .100" longer stems, with the heads cut down to 1.93" and 1.645" respectively to eliminate any possible valve head to valve head interference. The original valve sizes were 1.923" and 1.663" according to factory specs. There's simply no room to enlarge the valve sizes, they're just too close together.

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.
