Piston Rings

Hey people! My 340 engine, with 800 miles on it, had a really small oil leak between the head and block that it's had since it was rebuilt years ago. Last fall I took the heads off to replace the head gaskets. I was planning to use some MLS gaskets but the deck was way to ruff, but the heads are really smooth. So out comes the short block and I took it to the machinist who prepped my heads. He was amazed that it didn't leak worse than it did. The guy that did the short block is getting old and won't buy new machine tools and his quality has gone downhill. Anyway the block was .008 different front to back and the rod big ends were all over the place on the balance. He had to cut .015 off the deck to get it flat and square. Of course the pistons need the be milled now to be at zero deck, and balance the thing again.

This thing is going to cost me a lot more than a head gasket swap. So to try and save some money he cleaned it in his aluminium tank so I can reuse the cam bearings and soft plugs. I will replace the bearings even though there in like new condition, that's a given. But, the rings are Total Seal 2nd gapless and also in great condition. Can I reuse them or would that be stupid, especially if they don't seal. If not, what rings would you use for a 5/64's ring land piston? Not much choice for a 4.070 bore anymore.

Sorry for the long post but I have to decide this week what to do.
