Thanks for the info faztbullet. That is the what I was looking for. Now I have a question about ring gap. The part number for the rings that this website shows is
385663. This has been replaced with 396504. That ring fits many engines up through 1987. The book I have shows that a ring gap for my 1980 engine is .007-.017. I have bored my cylinders at 3.530 and put a ring in and I have a clearance of .023. This is on a brand new Johnson ring set 396504. When I compare that part number on boats dot net I see that it fits up through 1987 and that 1987 engine should have a ring gap of .020-.033. I believe that I have the correct rings, but thought I would get an opinion on it!
