Cometic Chevrolet Mark-IV Big Block V8 .050in MLS Cylinder Head Gasket - 4.630in Bore

Cometic Gasket is known for making well-built sealing solutions, and this Multi-Layer Steel (MLS) cylinder head gasket is a prime example. It's designed for Chevrolet Mark-IV Big Block V8 engines and features a .050 inch thickness with a 4.630 inch bore. This gasket is built to handle the tough conditions found in many performance and heavy-duty applications, fitting a wide range of vehicles from the 1960s through the 1990s, including popular models like the Chevrolet C10 Pickup, Impala, and Camaro.

The construction uses three to five layers of stainless steel, chosen for its strength and ability to resist corrosion and rebound under pressure. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps ensure a solid seal even in harsh environments and across different surface finishes, making it a reliable choice for rebuilding or upgrading your engine.
