How bad did I #$&% my piston up?

the top ring gap on the kb107 hypers is very important....should be up around .030 gapped...the second ring can gapped normal, with todays thought to be around .022 gap...
the kb107 top ring is higher on the piston and is subject to higher temperature ..and therefor needs to be gapped wider.

I have KB 232's in a .030 over bore. Now I'm starting to get confused, most likely because I'm reading too much into this. So I was told to use the formula of 4x4.000 for a standard four inch bore, or for my situation, 4 x 4.030 to determine the desired ring gap as the top ring sits inside the bore.

When I place that ring inside the bore, it sits at .0020, if I remember correctly. I can certainly go back and check all of those rings, too, though. So if I read this chart on Keith Black's webpage, anything from .0015" - .0020" for a normally asiprated engine with a bore size up to 4.100" is what you're going for, right?

It certainly doesn't seem like I want to file down or grind down the ends of the ring by any means because it'll just increase that size past .0020"?
