The hole in the block can be left alone. There is no reason to plug it. Plug the water pump housing hole.

An easy way is to knock out the factory seal, cut out a piece of thin aluminum to fit the hole, and use the factory seal to hold it in place. I have also used freeze plugs and even glued in a half dollar (in a rush!!).
