The oodles of Permatex is either a sign of insecurity or someone used to taking up Chevy machine tolerances. In my opinion, he needs to use a gasket. That's way too much and unnecessary use of RTV. I"ve seen excess chunks from situations like that end up clogging the drilled coolant passages (head to block mating). Got pictures of that. Also, seen it break loose and foul the oil pick-up.
