Cover+water pump question

I don't use any sealant with the factory captive-washer bolts, except the four long bolts, one of which holds the powersteering bracket, cuz coolant tends to seep out there if you don't. And without sealant on the threads, coolant tends to creep past the threads and into the cavity from there to the outside edge of the cover, where the water cooks out and the glycol then remains and fills the cavity, dries up, and seizes the bolts in there; making it very difficult to remove the cover many years later. The rest of the bolts get anti-seize. Except IIRC the one bolt on the Drivers side halfway down; I think that one also goes into the jacket.
I run a 7pound cap for several reasons, one of which is because the reduced pressure causes waaaaaaaaay less problems in the long run. But our daytime temps here in Manitoba-summers seldom exceed the 90/92, so our cooling systems have it easy.
