No water on the threads of the water pump bolts Alvin, they, all four of them, go into blind holes.
Gonna head out as soon as I finish my coffee and start to fill it again.
As a side note to this. This was a freshly rebuilt motor that had been completely degreased (baked out) and bead blasted before the machine work was done to it. So the inside of the water jackets were fresh raw cast iron. It had plain distilled water in it for no more than a few hours yet when I pulled the pump there was a nice orange film of rust already forming inside the water jacket and the water was tinted very slightly orange if held up to a light. That's a dang good example of how fast these blocks will rust without a rust inhibiter in the mix.
