Huh? Its dry sans the the one passage in the front. Pumps to block, then up to back of heads through to front, then out to intake then stat then radiator to feed pump again. The head gasket covers a passage that would allow pump water to go directly to front of head but if you open it, it will disturb the flow direction. You could block intake port with piece of aluminum can between gasket and intake and feed viavheater hose circuit...why?
