Ok, I got the odd-bank (driver side) head off. The cylinders are not overbored, but the OD is about 5 thou above nominal for all four (3.817). Measured carefully near the top of the bore with bore gauges and a good outside mic.
The valves mostly feel good but there's a couple that are a bit loose. 7 thou play on one and 10 thou play on the other.
Though I'm not against making repairs that are strictly necessary, I'm not trying to go full rebuild/restoration on this engine. So, I would appreciate any input from knowledgeable people on what the ramifications are of these things being a bit worn out.
Likewise I want to give all the internals a good cleaning. I imagine some type of wire brush and cleaning agent would do the trick but any specifics are appreciated. There is a lot of carbon buildup.
P.S. installed some safety pipes. Though it's nearly 200 lbs to lift the rear wheels off the ground.
