Coyote 5.0L Piston Rings - which is which?

[decipha]

I have a brand new ring set from ford for a coyote 5L and I can't determine which is the top ring and which is the secondary, the parts guy and ford tech had no idea either both rings look identical, one set has a green dot and the other an orange dot

anyone know?

Put them in the bore and check gap? The top ring should have a tighter ring gap.

The top ring will have a bevel or Back cut on the inside that is on the same side as the dot, the second ring will also have one but on the opposite side of the dot.

Best of luck, let us know if we can help!
