I would go with a thin layer of non hardening Permatex or RTV on anything around the water pump or thermostat housing. Reason being that unless the mating area was surfaced in some way and guaranteed absolutely smooth there could be some small corrosion pits. Something with a bit of body will have a better chance of filling and sealing any defects that might be prone to seepage under or around the gasket.
