Assuming you mean pistons, I have never seen a .010. The first size I have seen is .020. If you do not need anything more than .010, get rings, they usually come marked standard-.010. You will of course have to gap them.
If you are not part of the solution,
you are part of the problem!!!

John, I was told when I asked about this in my previous post what .010 over would require new pistons??
Thanks Craig

you got me curious about this so I did some searching. John is correct. All the 0.010 over rebuild sets come with rings only, and will have to be gapped to fit. You can get new pistons in 0.020.

Southern Outlaw, How exactly do you gap the rings? Will that have to be done if I bore .020 or .030 over?

yes it will have to be done. basically you use a piston to push the ring into the top of the cylinder with a piston to make sure it is straight and use a feeler gauge to check the end gap. If to tight, take it out and file a little off the eds and try again. The service manuals in the pdf manual section at top of page have more info. If you are taking it to a machine shop to be bored, get all the parts from them and have them do the basic assembly of the engine.

Since your cylinder bores are worn so much, make sure you set the end gap at the smallest (tightest) point in the bore or you risk having the rings bind which can lead to breaking the rings, pistons or seizing. At that point, then you'll do a real rebuild of the engine like you wanted to originally.....

Make sure you remove the ridge at the top of each cylinder too.

Why don't you take the time to read the engine rebuilding section of GSS1411? Most of these basics, like ring gapping, ridge reaming, are well documented in text and diagrams- plus many other issues that you probably are not aware of. We have all been there at some point. Time to learn the basics and the manual is a good place for you to start to learn the scope of the tasks involved in rebuilding an engine before costly errors are made.

John explained it as well or better than I can. It is easy, but time consuming.
