Chevy SBC 350 Intake Manifold Gasket Set (1207) 2.28" x1.38" x0.060"

Most Speedmaster intake manifold gaskets have Printoseal construction, which puts beads of special elastomers around the ports for extra sealing power. They also feature a non-metallic, rubber-fiber base material that resists gasoline and alcohol, while allowing engine builders to precision-trim around the intake ports.
