I looked closer at the cylinder walls. There is absolutely no ridge whatsoever. In fact, all the cross-hatching is clearly visible. I'm thinking so far that there is nothing I need to do to the pistons and cylinders.

The head parts will take a few days to get here. I have to find a shop in the area that can work on it.

I'll start taking the rest of the engine out. At minimum, I will get a new oil pump. I will take a closer look at the crank, bearings and journals.

Thanks much for the info on preparing and renewing the head and block surfaces.
