Stop in for a cup of coffee

quick question; how rough should cylinder walls be when using stock style piston rings in a semi-hot 318?
320 grit? 400?
Welcome back! First, I don't use "stock style rings". They are regular cast iron and unfaced. I use moly rings on everything. I would step up to something better were I to build something like a race only deal....which I likely will not do again. The moly rings will be fine. I use ball hones from 360-400 and call it good. It's always worked for me and I scarcely ever have one even poof out one puff of smoke even on initial startup.
