Hey BigJack... thanks for your feedback. I am totally in agreement regarding your point about the precision of the mating surfaces. Unfortunately I do not count on this level of quality from the parts made today. I had never thought about anti-seize as a sealant, but it does make sense. I'm going with Permatex this time as I believe the next swap of the water pump will coincide with a complete engine tear down and overhaul. You made some great points - thanks!
