I have one customer that freshens a stable of motors regularly. These are blocks I've sleeved so the have zero wear on them when I see them. I hone them with the much maligned dingleberry hone (400 grit) and get perfect profilometer numbers. I run the hone backwards for 10 strokes, then 10 strokes normally. Even though they seem on the mickey mouse side, they are actually effective for "surface conditioning".
