An air intake manifold gasket has a perforated core of metal including protrusions or tangs extending from a first planar surface and a second planar surface of the core. Joined to each planar surface of the core is an expanded graphite sheet to form a gasket body having planar surfaces. Screen printed to form a bead on peripheral edges of the planar surfaces of the gasket body is a silicone foam rubber material adapted to replace traditional silicone rubber structures used for the same purpose. The silicone foam rubber material includes a foaming agent that causes the material to expand during an oven-curing period. The amount of expansion of the silicone rubber coating is up to three times the thickness of the coating originally applied. As disclosed, the oven cure is for approximately 10 minutes at about 300 degrees Fahrenheit.
