The set is explicitly for a 4.17 bore so they should be right. I took an oil ring out of the bore, gently flexed it up and down a little bit, then put it back in. The gap opened up to .015, so maybe they just need some slight persuasion. Doesn't feel good doing that, but they're pretty thin rings.
Just to confirm for the compression ring gap, I'm hearing .023 on the first and .025 on the second?
Interesting old post (#16) by mgarblik on ring gaps and how wider doesn't impact performance. HWYSTAR, you make an appearance in the thread too:
