Deglazing and with a 3.910 std bore they all cylinders are under 3.913 is the largset measurement I can get but I got this ring you can see in picture. Do I need to keep going. This is not a race motor
If you can slow the drill down, and increase the speed of the stroke, maybe spend a short while trying to get a 45* cross-hatch as in pic.
Helps seat and lube rings, otherwise, good job.
