Everyone has their own ways, but I would never use grease on todays paper gaskets, they are sometimes poor enough without the grease swelling them and having possible premature failure.
the only gasket that need extra help are the oil pan, which I use permatex aviation gasket maker on pan side only, then ultra black where the end caps meeting the sides
chain case cover- av gasket maker both on gasket and on seal before I drive into the cover
water pump- just a few small dabs of gasket maker to hold gasket for install
head gasket- permatex copper high heat gasket spray on both sides on gasket (follow instructions on can)
intake shoukd need nothing unless its pitted, exhaust same thing, unless your installing headers
hope that helps
