Yes, I actually want to know about ridge reamers. I know it's not the most popular thing to do but I'd like to shave the .002" ridge off the tops of the otherwise straight and smooth bores in this 440. I already have pistons and rings that are within tolerance for this engine and don't feel the need to drop the funds to bore it and buy new stuff.

Setting up the block in my mill would be a major PITA since I'm not set up for engine work. This is a low power application and should be fine with reaming. Slamming rings into ridges is not on my favorites list.

What kind of reamers have you guys used and how well did they work? I know the results will be no better than the person doing the job.
