Your casting number indicates a block without water passages for watercooled plug head castings. The head casting you list has a water passage for water to cool plug area. I have seen 3732791 blocks with the material present so you could drill the holes in the deck for your heads. I have not seen a block with your casting Number with the proper material. If the material is not present you would have to block that part of the head where the water passage is present. I have seen JB Weld used, but I would not trust that and would probably have to have them welded.
