As been stated before by others on here, the Pontiac crowd is in a learning curve on the differences of aftermarket blocks that the competition is used to. I would think a call to Bob and Frank at All Pontiac would resolve any issues the starter of this thread has. Also calling people who have experience with the IAII blocks such as the engine builder like P Dude or any of the others here would certainly be a worthwhile call.
