4.0 ring end gap

[tarmac2dirt]

Hello, building a 4.0 for my jeep Comanche. This is a stock rebuild not a stroker. i have started checking all the gaps and clearances and have come up with no recommended ring gap for parts i have bought. The pistons a sealed power h802cp and matching ring set. There are no ring gap notes anywhere in the boxes, as compared to the stock pistons the sealed power pistons are hypereutectic and i know the ring gap needs to be wider than stock specs. i have come across the Keith black spec chart and it shows .0065 per 1" of bore dia. Is this applicable to all hyper pistons?? Out of the box i have .017 on my top ring and .017 on 4 and 2 at .018 on the second ring gaps. Keith black hyper specs calculate to about .025. should i go with .0065 calculations? comparing the stock and new pistons the top stock top ring land is at .321 and the new hypers are at .245, much closer to the top. I have also decked the block .020. What would be a some of your suggestions for the proper end gap. This engine will be a dd not needing any performance of race type specs. Thanks for any advice, Paul
