I surely wouldn't touch those pistons and I see no reason to touch rings with leakdown under 10%. Put the thing back together and have some fun. Don't make this expensive and time consuming.
Pretty much agree. Either fix it correctly or don't mess with it. But ME... i'd send the pistons to Rebco have a convo. He'll answer all the concerns you have aired here. Depending on where the bore cleaned-up, i might coat the skirts. Rebco can gas port cheap too...maybe put a napier second and fix the ring pack however he recommended. how is P-2-V? all these things I'd consider MYSELF but it sounds like your after a budget build. Odd because it looks like there may be some good pieces there.
