It seemed mostly just to be gone. Not all areas were all that contaminated beyond a little discoloring. Around #1 & #2 there were deposits stuck to the surface of head and block that I interpreted as carbon and maybe gasket material. #3 & #4 were much cleaner, though cylinder top #4 was just as gummy as #1. I did the razor cleaning of the block mating surface, and though I did not want to dig too hard for fear of gouging some of what flaked-off the block must have been gasket material.

That was nearly my exact situation. And checking frequently revealed it had suddenly gotten much worse in a couple hundred miles. Still was not nearly fully blown, btw. But unmistakably headed toward the death of the engine without intervention.
