“The camshaft woodruff key didn't sit well in the groove and I broke one cam gear on install, and another on disassembly. The machinist uses a non-Pontiac one that has a flat bottom and nests better, solving this issue”
Say what?.........please post a pic of the cam that was removed....especially the cam snout and key way. This seems highly unusual?
If the cam was indeed broken on install, you have the catalyst for the rest of the damage?
