My studs never leak.
I use black high temperature RTV and screw them in wet, finger tight, then back them up 3 degrees. I let them sit overnight that way. The next day I clean up any squeeze out with acetone so the silver paint I use on the gasket does not get contaminated.
I machine the first thread out of the stud holes so it doesn't get pulled above the deck when torquing.
When I have the block in the mill I also tap the head stud holes with a standard tap.
I want the studs to seat square with the deck on bare clean metal.
