The Delco/Rochester bulletins dated may 1967 and later have the #7015345 gasket for 1959-66 Pontiac Tri-Power end carbs, and since they work, why not?
The reason for the vented gaskets does not vary from center carb to end carbs or the year of the Tri-Power.

Yes, the closed base gaskets will work OK on end carbs for all years, but the vented gaskets, which are included in all kits also work. I see no downside of using the vented gaskets. It is true, however that the holes added to the throttle plates in the end carbs do create enough air flow to keep the throat of the carbs free of vapors unless there is excessive fuel leakage.

About Us

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.
