It all depends on how big of a step there is between the intake and the head. Generally, I use a cork gasket, put a little RTV on the joint between the head and intake, then smooth it out so that it takes the step out. Try to make it a smooth transition, so that they are level with each other. I don't use any adhesive at all on the gaskets and just tighten them by hand.
It also helps if the heads don't let the
oil pool in the top end.
