The intake gaskets sets from autozone and advance auto made by Felpro are like $10 at most and come with 7 pieces. The upper intake gasket, the IAB gasket, the o-ring for your dizzy, the lower intake to head gaskets and two nice shiny blue rubber gaskets that go where your screw driver is. One for the front and one for the back. You ONLY put sillycone at the four corners where the intake to head gasket meet the rubber gaskets and it just takes a tiny bit.
For as cheap as the gasket set is (I don't like the cork ones, personal preference) I can't see justifying laying a bead of silicone in there. Do it right, spend the $10. The silicone is then a bitch to clean off things when you remove the intake for other repairs or modifications. Then you get it down in your oil and maybe in the passages.
