Cometic Chevrolet Mark-IV Big Block V8 .050in MLS Cylinder Head Gasket - 4.375in Bore

Cometic Gasket is a well-known name for creating solid engine components, and this Multi-Layer Steel (MLS) cylinder head gasket is no exception. It’s built for Chevrolet Mark-IV Big Block V8 engines and features a 4.375-inch bore, specifically sized at 0.050 inches undersize. This gasket is designed to handle the tough sealing environments found in many performance and heavy-duty applications across a range of Chevrolet vehicles, including models like the C10 Pickup, Impala, and Corvette from various years.

The construction uses three to five layers of stainless steel, chosen for its strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C). This combination helps ensure a reliable seal under demanding conditions and across different surface finishes on your engine block and cylinder head.
