That's awesome, Buddy!
Always had a sweet spot for Pontiacs, I had a 65 GTO Tri-power 389 with an M-21 way back when.
So are cheater cams still flat tappets or do they run rollers in Stock now? I'm so out of touch anymore.
Pontiacs and mopars have at least a few cool similarities, particularly the port sizes and Siamese configurations are pretty comparable. Pontiacs seem to like a lot wider lobe separation for some reason though and seem to make there best power under 6500.
If I remember right, Pontiac valve covers are interchangeable with SBC's
