I believe the aircraft info is relevant as what's bad practice for one engine is bad for all engines.
Interesting side note, on the Cessna forum many of the Cessna engines are showing the same type of premature cam and follower wear problem that Jim Comstock and others have had with their Norton engines. The Cessna owners are muddling around, looking at oils, talking Zddp. Some have been using the Aeroshell oil that failed so miserably in Jim's test.

As mentioned, my own experience with removing and then reassembling used pistons and rings in bores without hone and re-ring has shown that there is something to the belief that well seated rings are best left undisturbed , if possible. I did quite a lot of small motorcycle engine rebuilding at one time.
I just mention this in passing. Of course everyone is free to do things any way they wish!
