What is the consensus on an O-320 E2C (wide deck) that has been "converted" to a B3A by putting in high compression pistons, that had all cylinders "honed" at the overhaul, all the valves, guides, seats etc replaced, and after 600 and change hours has gotten compressions in the 68-74 range year after year. The compressions on each cylinder have hovered in that range for 18 years, with one cylinder occasionally jumping up one year but other than that consistently down in the high sixties to low seventies.
I have not put a compression tester on it myself, or seen it in the flesh, so I can't say whether or where there is leakage.
