Trw .030 over forged pistons.

Only a sealed power piston isnt a standard piston, and I dont know what aftermarket .030 over pistons use.

I was saying that as an example. As in a STD piston takes a STD ring, a .030 piston takes a .030 ring, a .040 piston takes a .040 ring and so on. I didn't "THINK" I needed to go further. I guess I was wrong. You get whichever rings match the piston. If the pistons are .030, then get .030 rings.
