I did something pretty dumb today, I took my piston rings out of the box before looking to see which one goes ont the top piston groove, and which one goes in the middle groove. D'OHHHH.

They are moly rings, the rings which I believe are the top compression rings are a flat dark gray color, they have a small indentation near the gap( my rebuild book calls this the "PIP") the other side of these rings have a tapered edge on the inside.

The next set are close to the same flat dark gray, however these have a silver band running through the center along the circumference of the ring. There is no "PIP" or tapered edge.

So can anyone tell me which is the top rings? Thanks alot.
