L1ftmech glad to hear that you got things sorted out. I know at one time GM was only selling gaskets and seals the pistons and other hard parts were not available. I believe I may have a GM break down from when they first used these in industrial applications. If I can find it I will send you a copy.
About 5 or more years ago you could google any of the GM industrial engines and find the parts manuals on line but it seems they have all been taken down.
