There are two (2) raised sections on the front cover between the bolts underneath the water inlet holes. The raised sections are put there to put a higher load on the water pump gasket in that area. Should you experience a leak in that area when transferring the water pump to a Goodwrench engine, apply a RTV sealer to each side of the gasket. Do not grind off the raised section.
