I always try to use 320 grit to do my cylinder glaze breaking. Back when I did kart motors when I'd freshen a motor, we used moly rings, but I wanted to leave a nice cross hatch after the rings had seated and the 320 had gotten worn away, so I had a 180 grit hone I slipped in and out of the bore about 3 times and then went back over it with 320 to knock off the rough edges. Helped retain oil and after I started doing that my motors came back with less piston scuffing.
A 320 grit Ball hone should do the job, you can't really remove any material from the bore with the 320, so go to town on each cylinder...

I always used a little WD40, but now I take a coffee can the size of the hone and fill it with parts washing fluid... works well,dip it in, drop it in the cylinder and go to town, then drop it in the fluid and go to the next cylinder. If your honing one cylinder for an extended amount of time, then keep it good and wet..

Most auto parts stores can get them, i forget the size you'll want to order. I do know that they will be called "Flex Hone"
