I did cylinder 1 ring gap check…

Top ridge: .103
Top: .129
Middle: .066
Bottom: .063

.129 - .063 =0.066

.067 divided by 3.14 = .021

So…. Guessing .030 over might be what I can expect (or more).

(I will be bringing it to a machine shop clearly).

(I wonder why the top ridge is bugger than bottom of cylinder… previous backyard re-ring?)
