Wrong or too rough finish will only let some oil in for some number of miles and allow the rings to eat cylinder wall faster.
If you didn't have a ridge...you will in no time if you fk up the finish and use the wrong ring.
I know... I sound overly critical. That's just me I guess when it comes to doing some things myself. You know if you paid some machine shop to do it and they did it the way some here plan on doing it you'd be pissed with what you ended up with ...so why would you do it the same shitty way yourself.. is how I look at it. hope it's not always about saving money when it comes to labor/technique. Maybe it's that "I could do the same **** myself and not pay somebody" attitude that's coming into play.lol idk
But..hey...let's not overthink this just break the glaze and throw some new whatever rings in there, pour the cheap 10w/30 stp oil into it with one quart Lucas oil treatment and let'r rip.
