Chevrolet Mark-IV, GM Gen-V/VI Big Block V8 .045" MLS Cylinder Head Gasket, 4.570" Bore, For Aftermarket Heads - Undersized Water Ports to Allow for Customization
Cometic Multilayer Steel (MLS) Gaskets are designed to provide the best possible seal for naturally-aspirated, boosted, or nitrous-fed engines. The head gaskets are made from 3-5 layers of spring stainless steel, offering a stronger base material than standard cylinder head gaskets. Viton-coated stainless steel outer layers create a superior seal not available with other steel or copper gaskets. MLS Gaskets reduce bore distortion, resist corrosive substances, and have excellent rebound qualities. Sold individually.
