Cometic Chevrolet Mark-IV Big Block V8 .045in MLS Cylinder Head Gasket - 4.320in Bore

Cometic Gasket is well-known for making durable engine sealing components. This Multi-Layer Steel (MLS) head gasket is built for Chevrolet Mark-IV Big Block V8 engines, featuring a 4.320-inch bore and a compressed thickness of 0.045 inches. It's designed to handle the demands of high-output engines and fits a wide range of vehicles, including models like the Chevrolet Impala, Corvette, and C10 Pickup from various years.

This gasket uses multiple layers of stainless steel for increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in harsh conditions. MLS gaskets are suitable for combinations of aluminum and cast iron heads and blocks, as they can manage the shearing forces that occur between different metals. They don't require any additional sealants, making installation more straightforward.
