On studs I use Indian Head shellac.

I like to wait about 24 hours after setting them into place before putting on the gasket and head. This allows the shellac set up a fair amount but still allows the studs to be turned by hand with a little bit of effort. This then makes it possible to adjust the amount of the stud that protrudes above the nuts if they are too low but is still stiff enough to prevent them from turning when spinning on the nuts.

Lacquer thinner works well to remove any shellac that squeezes out of the threads after screwing them in.
