For assembly, I put all ring gaps at pin centerline. That puts each gap 180° from the one above or below it. With that said, as sprint250 said, the rings will rotate around until they find their own happy spot, so it's not like it's a make or break deal. I just like to start out with gaps as far away from each other as possible. I also don't like having the gaps in line with the piston skirt. Then the thrusting of the piston try's to jam the ring gaps into the cylinder wall which makes scratches in the cylinder wall more likely.

I was wrong once. That was when I THOUGHT I made a mistake!
