I finally got around to checking the valves. This motor was supposed to be a low-time motor when I installed it and I was in a hurry so I didn't check it out too thoroughly.
Anyway, this is NOT a low time motor! The valve adjusters are worn at a slight angle and the cam has noticeable (but light) grooves where the cam followers ride. That explains the metal in the oil analysis!
The good thing is the figgin' thing still runs like a scalded dog. So, we left everything as it was (the valves were close enough) and closed it back up. I'll run it as-is another season and start buying parts for my spare motor.
I've always been told these motors are rock solid and now I'm a believer!
