Cometic Chevrolet Gen-1 Small Block V8 .075in MLS Cylinder Head Gasket - 4.200in Bore

This is a Cometic Multi-Layer Steel (MLS) head gasket designed for Chevrolet Gen-1 Small Block V8 engines. It features a 4.200-inch bore and a compressed thickness of 0.075 inches, making it suitable for a wide range of vehicles from the 1980s, including models like the Chevrolet C10, Camaro, and GMC C1500. MLS head gaskets are built to handle the demands of high-output engines and are known for their excellent sealing capabilities without needing additional sealants.

Constructed with multiple layers of stainless steel, these gaskets offer increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes. The center layer is stainless steel, allowing for different thickness options to meet specific engine build requirements. These gaskets are also designed for aftermarket heads, with undersized water ports that allow for custom fitting during installation.

This gasket is a solid option for rebuilding or modifying your Gen-1 Small Block V8. It's designed to work well with both aluminum and cast iron blocks and heads, and can withstand the shearing forces that can occur between different metal types.
