Maybellene/Jerry,
Hadn't considered sleeving all of the cylinders and bring it back to stock or a little over. The longevity of the engine would vastly improved and it would have more opportunities to be rebuilt if needed in the future, as you stated. Of course that is the most expensive route and would require a new set of pistons. I'm trying to keep this project on a minimal budget overall but there are things I don't mind splurging on if I don't have the skill set to do it or it is just the smart thing to do.
