Took the engine in today. Mechanic thought the cylinder with the light colored exhaust valve was running okay, but said the color should be a bit darker.
He didn't like the hash marks in the cylinder. Made lots of grumbling comments about people who don't have the right equipment or use the wrong stones for the rings (or something of the like). He thought the hashes were too deep, as I believe somebody has mentioned. It's a good chance it'll get bored out to 040 to ensure a nice round hole with a good, appropriate finish.
He says the wear pattern of the bearings is pretty typical. We'll see how far down the grind needs to go.
Thanks again for the advice,
