I only use top of the line gaskets (FelPro). That said, I lay them in place with about three drops of gasket cement to hold them steady. Then a 1/4" bead of black silicone along the front and back rails of the block, and running about 1/4" up onto the side gaskets. Then drop intake straight in place. Use your favorite sealer on the bolt threads. Torque in place.
I worked at my local GMC dealer back when they issued the service bulliten advising to never use the rubber end seals and instead substitute silicone. It drastically cut warranty oil leaks when they started doing it this way.
