Need advice and opinions on which piston ring sets are best for me. 4.125 is the bore and 1.52mm is the 1st and 2nd ring thickness followed by a 3.02mm oil ring. Difference between gapless and non-gapped rings? And what kind of oil tension should I be looking for, Standard, High or low? Thanks

 

I use Hastings rings, for every thing I have built. The machine shop that I used to use, did all kinds of engine builds, and that is what he used, and recommended on all his engines he built, stock to high performance.
