Spend the couple hundred dollars extra by buying new oversize pistons and having the block hot tanked, bored, honed and new cam bearings installed. Why go through all the trouble of doing this just to cheap out on the most important part? I've done budget re-ring jobs before but only when reusing the stock pistons. Once you start toying with changing pistons and dealing with ridges, you're best of just to spend a little more and do it right.

FWIW, I think a smogger 440 piston had a compression height of around 1.912 if memory serves. A far cry from a 2.060 of a 6-pack piston!
