Severe blow by can cause stuff like that. I've also seen hardened valve seats crumble to pieces. Stellite is kind of a funny material that can do some weird things when exposed to the right (or wrong) conditions. The old cast iron quality left a lot to be desired too. The modern mixes are a lot more resistant to stuff like that. It's kind of like a heat corrosion or erosion.
