I'd never use used pistons and rings in an engine build. To me that's asking for trouble. The used pistons are worn into the bore of the engine they came out of. Your engine's bore won't be exactly the same. Take your block to a machine shop, have them measure the bores and then order pistons according to what they say. Chances are you'll need .020" over pistons.
