also - your gasket is blowing out because either surface is not flat or you've hogged out your transfers too big. a k100 doesn't vibe that much to loosen the head bolts i would think - maybe your motor mounts are loose and it's the problem?
i forgot to mention my base gaskets were blowing out because i have the transfers at just about as big as they will go, and have very little flat surface for the gasket left. copperkote will probably solve the problem.
