How much honing would it take to get out a cylinder wall scratch, just deep enough to hang a fingernail on? I have a 99 block and rotating assembly, but two cylinder walls have scratches that are straight up and down the wall, the length of the piston travel. I'm hoping to have just a small amount of honing done, and use the .25mm oversized rings that GM put out. Is this possible, or am I looking at new pistons too?
