Sanded and painted the engine block today.

Then I installed the water pumps permanantly, and test fit the timing cover.

I had to shave a slither of the thickness from two places on the timing cover. The new water pumps are a tiny bit thicker around the bolt holes, and it was easier to shave the timing cover, instead of trying to unstick the water pumps. I had used aviation gasket sealer on them. I'm sure the gaskets would have come away in pieces!
Robert, this photo is for you.
