[Russ/40]

All valves are trash, look like the lash was ground with a hand grinder. Half were burnt, all were ground to sharp edges. The cam shows peculiar wear due to the foot of the lifters have a hole in the center. The aluminum gear is a pretty new, but chewed up by an incredibly rust pitted crank gear that only an idiot would reuse. That entire valve train is trash. The bores look very good, but they are still holding the rotating assembly. Next access the babbit and bearing shape.
My guess on the valve lash was wrong, I was expecting a few flat lobes. So you who guessed someone crazy with a grinder nailed it.
