About this part

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket is built with a 4.300-inch bore, specifically designed for the 1969 Chevrolet Camaro ZL1 Mark-IV Big Block V8 engine. MLS gaskets are a strong choice for high-output engines because they are made from multiple layers of stainless steel, which gives them increased strength and resistance to corrosion. They are also designed to handle the shearing forces between aluminum and cast iron blocks, making them suitable for a variety of engine builds.

The outer layers of this gasket are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating ensures a reliable seal even in harsh conditions and across different surface finishes. The center layer is uncoated stainless steel, and its thickness can be varied to meet different sealing requirements; in this case, it's set to provide a compressed operating thickness of 0.098 inches with an initial thickness of 0.027 inches. These gaskets are designed to seal effectively without the need for additional sealants.
