Re: Quick Question

I usually use the permatex aviation form a gasket, the brown stuff in the can with the brush under the lid. it works pretty well on threads that are not pristinely clean. just make sure the threads go into the water jacket as you go, otherwise, if it is just a blind hole with no coolant contact, use oil on the threads just to ensure lubrication.
some guys swear by the GM branded head bolt sealer. not even sure what it's called anymore. some guys swear by the newer Permatex® High Temperature Thread Sealant, which lubricates as well as seals and is intended for head bolts and other high temp uses. you could google the permatex page if you wanted to check it out
