Cometic Chevrolet Mark-IV Big Block V8 .084in MLS Cylinder Head Gasket - 4.320in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring Viton rubber coating on the outer layers. With a compressed operating thickness of .084 inches and a bore size of 4.320 inches, it's designed for Chevrolet Mark IV Big Block V8 engines. MLS gaskets are a solid choice for high-output engines because they offer maximum sealing performance without needing additional sealants, making them suitable for combinations of aluminum heads with aluminum or cast iron blocks.

The strength of these MLS gaskets comes from their layered stainless steel construction, which helps them resist corrosion and maintain their shape under stress. The outer layers are coated with Viton, a heat-resistant rubber material capable of handling temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in demanding conditions. The center layer is uncoated stainless steel, and its thickness can be varied to meet different requirements, allowing for precise gasket thickness.

This gasket fits a wide range of Chevrolet vehicles from the mid-60s through the early 90s, including popular models like the Chevrolet Impala, C10 Pickup, and Camaro. It's a well-built component for rebuilding or maintaining your Big Block V8.
