Anyone ever checked the ring gap on a .020 over bore at the max Cummins spec of 4.040? Everything ive found says .014-.025 gap. I'm trying to figure how much the extra .004 bore can effect the end gap. I'm setting at over .045 gap and when I stick the .020 ring in a std bore it's still over Cummins spec. So I'm trying to figure out if the rings are cut wrong. I've gotten 2 sets and they both fall into about the same gap just way to big.
