Cometic Chevrolet Gen-1 Small Block V8 .080in MLS Cylinder Head Gasket - 4.160in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with a compressed operating thickness of 0.080 inches and a 4.160-inch bore, making it a solid choice for Chevrolet Gen-1 Small Block V8 engines, especially those running aftermarket heads. The gasket's construction features multiple embossed layers of stainless steel, which offers increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material designed to handle tough sealing environments and various surface finishes, ensuring a reliable seal between aluminum heads and blocks, or aluminum heads and cast iron blocks.

The center layer of this gasket is uncoated stainless steel, allowing for flexibility in thickness requirements. This design helps manage the shearing forces that can occur between dissimilar metals like aluminum and cast iron. Because it's an MLS gasket, it requires no additional sealants, simplifying installation. The water ports on this specific gasket are undersized, which is a thoughtful detail for builders using aftermarket heads, as it allows for custom fitting to your specific setup.

This gasket is suitable for a wide range of vehicles, including many Chevrolet and GMC trucks and cars from the early to mid-1980s, as well as models like the Avanti II and Checker Marathon. It's designed for high-output engines and provides maximum sealing performance.
