Heads, valve covers, intakes, and exhaust manifolds. The V12 was really a pair of the 351 V6 motors in a common block with a common crank.

You mean "none of THE other GM I6 compared". The only I6 motors in that time frame were the Chebby I6 and it's related Pontiac OHC motor.

Unfortunately, like the Pontiac Aztek, I6 Cutlii are rare for a reason.

Pontiac had 2 versions of their OHC 6, the Sprint option was a great engine. It was ahead of it's time when V8's ruled the roost. It has a pretty good following and is collectable.
