If you take the time to hone and install new rings, don't ball hone it, take the cylinders to a machine shop where they can do proper job of honing that'll remove 'some' out-of-roundness and keep the taper to a minimum. A ball hone just scratches the high and low spots and this is really what you'd like to get rid of along with any glaze. You may end up with a slightly larger ring gap than you'd like but you will be better of in the long run.

I'm not sure you can do that with nikasil, it's a thin coating you don't want to go through. Being as hard as it is they may not be that much if any out of round. If damaged or out of spec it has to be recoated. When boring cylinders we always allowed for a couple thousands for honing. I'd measure before using anything except a ball hone.

Shouldn't really do anything to them unless you can verify the thickness of the coating.
