Piston ring gap?

[EMW150]

If they're for a 4.030 bore they're probably presized and won't require any filing on any of them. (You'll want to check them though) Usually file fits will come like 4.035. Oh, and it's rare to ever have to file oil rings. I've never done it but some of these guys are saying Total Seals do. That's rare.

Also these are going on keith black hyper pistons. Their website recomended .0065 end gap for my application? Not sure what they mean by this?

are you sure that's not piston to wall clearance?

Ring gap minimum.... I'd say .017 for a N/A engine. I run mine .017/.019
