You just came close to giving a couple of the folk here mental duress.

Anyway, the problem could be valves or rings or both. Could have worn cam also. The only quality repair is a full rebuild. That being said, dropping the rotating assembly from the bottom is a royal pain, and re- ringing without a bore is sloppy work.

BUT. If you mike the cylinders, and they are nominally free of taper or oval, then you can cut the ridge, hone, and have a reasonable repair. No way to do that without pulling heads, so you may as well lap the valves. It's cheap and easy.
