.005 oversize rings on std piston ? SBC

I have an engine that sat with water in the cylinders causing some pitting, honed it to clean up, was rebuilt recently with std pistons, I don't have a bore gauge but measured ring end gaps and they seem a little wide, .028, Should I try to find some .005 oversize rings? Daily driver not a race vehicle.

If you are that curious, buy a set for one piston and check the cylinders at bottom of ring travel. I suspect the gap will be overlapping. A gap of .028 on a rering should get ya going for a while, but it is not going to be perfect.

I have a 350 block that got some water in it and caused some pitting, I tried to hone it, but did not get all the pitting out. wouldn't the pitting cause it to burn oil? and not hold correct compression?

Need maximum results? Stop guessing and research basic 350 sbc builds. Boring the worn, damaged block w/a torque plate will ensure the bores are straighter than factory. Smoother running, more efferent. Patch it and go, or save up and have a far better engine.
