Thanks Schmidtys, I will post a picture later. I started sanding the face of one of the valves - finally got down to a bright spot of metal. There is a thick deposit of a ceramic-like material on the face of the valves, kind of tan or grey that sands without too much difficulty, but it's tough stuff. It looks like the only way to get it off will be to abrade it.
Interesting, what kinda crap are we burning.
