Not sure if there’s a post on here about ring gap but I’m gonna open a can of worms here and ask and see if anyone will let out their experience with what ring gap have tried thst has worked out really well and taken some serious heat without any issues at all, I have read racing blown supercharged engines running .028 gap and another article up to .040 without affecting compression more than a couple psi I realize there are a lot of variables type of ring and pistons material and having a freshly bored cylinder vs worn out tapered cylinders and there’s lot of secrets ppl don’t want to give out but if anyone has lotta experience and knowledge or retired and wants to help other ppl this post is to help other builders too with same question as to what works well without going too much and losing too much compression yet has gotten engines extremely hot without ring gap being issue and has ring gap been more of issue than valve guides and material or more valve guide problems before rings when taking on extreme heat I have heard valve guide material in new dart iron Eagle heads should be clearanced or changed out for dependable derby use and the world products use cast iron guides and is more forgiving
