It would appear the intent behind my post wasn’t made clear.
The OP has a .002” ridge (or, 1/2 the thickness of a dollar bill)he’s worried about. I’m saying......... don’t worry about it.
Ball hone it and put it back together.
I’ve re-ringed stuff with way way way more ridge than that....... no ridge reaming...... motors ran just fine for years.

If not exceeding the worn part of the bore, ridge reaming won’t hurt anything. I don’t see how it could be argued that leaving a step in the bore is better than removing it. If the argument is that the ring doesn’t travel far enough to matter, than how does it hurt to remove the step?

I’ve re-ringed stuff with way way way more ridge than that....... no ridge reaming...... motors ran just fine for years. I agree Thought you meant you could take the .002 out with the ball hone in less than a minute. Heck I have heard of people running moly rings on an untouched worn bore successfully. I've never done that. The new rings will run up past the ridge. The idea of new rings smacking into a ridge several thousand times per minute does not sit well with me. Running a three stone hone in the bores (assuming they survive impact with the ridge) will angle the stones and create a wide spot in the middle of the cylinder due to the angle of the stones. Dingle berry hones will likely smooth the transition somewhat. However, they will not remove the .002" ridge without putting a .002" hone deeper in the hole as well. When you're done, the bore will look to have the same finish all the way down but there will be bore diameter variances along the way. That's just physics. Every ball removes metal, not just the ones you want.

Every ball removes metal, not just the ones you want. I think before you are done with this you are going to regret not just going .030 over. I think the chances of using a ridge reamer to remove just .002" and still be anything close to a machinist's definition of round are pretty slim. Somebody suggested the stock piston to wall clearance is a few thou tighter than your forged pistons need and you could bore and hone it to the forged piston to wall spec. At least you stand a chance of having a rounder straighter cylinder than what you have now. Kevin
