+1 on replacing the liners, all of them, when doing an overhaul. During one overhaul, my machinist told me that 1 of the 5 cylinders was within specs and didn't require a new liner, so I saved a few $$. While the engine ran fine and and I had no complaints power wise compared to before overhaul, the cylinder with the old liner read 10 to 15 pounds lower when compression was checked. I'm sure when miles got high enough that cylinder would be the 1st to have cold start problems. Don
