Re-hone or New Rings?

Crosshatch looks nice, no wall or piston damage

Moper - I want to avoid an overbore with new pistons. So rehoning and using moly rings is better than cast irons? Somehow I was under the impression that cast rings would seal up better on a used, honed bore. As for the 2nd ring, you're saying add .003-4 more gap to the stock, oem limitation?

Ballooning is a concern, I'll have to inspect the converter and look for signs. I'm running about 400-450 torque I'd estimate. Boost begins at 2500 rpm. Max rpm is 6000
