Cylinder Honing
I've recently pulled one of the pistons out of my 302 to replace broken rings. I've noticed that the other pistons have a lot of carbon buildup on them. I'd like to clean all of them off, and I've had someone reccomend to me that I hone out the cylinders while I have the engine apart.
What I am wondering: If I hone the cylinders will I have to get oversized rings, or does honing just clean off glaze from the cylinder walls?
Also, is it bad to clean varnish off of the connecting rod bearing surfaces? I read that you shouldn't clean off any varnish from the main bearing surfaces on the engine block, and I'm wondering if its the same for the connecting rods...

Is it apart and in the truck? If so I would leave it alone. If not removing the other pistons is just time. The block should be cleaned with soap and water after honing. If you have a nice cross hatch pattern in the cylinder you shouldn't need to hone. Honing does not take of much material at all if done properly. The idea is to have the cross hatch pattern to retain lubricant between the rings and cylinder walls.
