Cometic Chevrolet Mark-IV Big Block V8 .095in MLS Cylinder Head Gasket - 4.320in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built for Chevrolet Mark-IV Big Block V8 engines. You get one gasket, made with multiple embossed layers of stainless steel and coated on both sides with Viton, a heat-resistant rubber material. The compressed operating thickness is 0.036 inches, and it has a 4.320-inch bore, making it suitable for high-output applications. This gasket is designed to provide maximum sealing performance without needing additional sealants, and it works well with both aluminum and cast iron blocks and heads.

The strength of these MLS gaskets comes from their multiple stainless steel layers, which also help them resist corrosion and maintain their shape under stress. The Viton coating on the outer layers is designed to handle harsh sealing environments and varying load conditions. The center layer is stainless steel and can be varied to achieve different thicknesses, like the 0.095-inch specification on this particular gasket. This construction is ideal for engines that produce significant power, as it can withstand the shearing forces between different block and head materials.

This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the early 80s, including models like the Chevrolet Impala, Camaro, and C10 Pickup. It's a solid option when you're rebuilding the top end of your Mark-IV Big Block V8.
