I always use spray trim adhesive on all my gaskets except carb gaskets and head gaskets which I use nothing, just lightly spray the gasket and then lightly spray where its going to be and wait a few minutes for it to tack up and then put the gaskets in place the adhesive holds the gaskets firmly in place so you dont have to worry about the gasket(s) shifting around during fitting up and assembly and also when you disassemble there no mess to scrap off either. Save the "permatex" or "form a gasket" for the ends of the intake manifold and the corners of the oil pan. It really makes for a clean motor not having that unsightly permatex oozing out all over the motor, plus it wont be oozing out inside the motor and stopping up your oil pump pick up.
