Go with the 6X's ! They have hardened valve seats and screw-in studs and are excellent heads ! Valves sizes are 2:11 intake and 1:66 exhaust...inches.

I would not go with either if this is for a 350. 6X-8 heads will give you really low compression i'm guessing 7.6:1. Find some heads with a chamber of 72-80cc's

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.
