About this part

Product Details

This product is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevy Gen 1 Small Block V8 engines, specifically for use with Vortec heads. It has a compressed operating thickness of 0.120 inches and a bore size of 4.080 inches. This gasket is built to handle the demands of high-output engines and is suitable for applications using aluminum heads with either aluminum or cast iron blocks, as it can manage the shearing forces between different metals.

The construction features multiple embossed layers of stainless steel, which provides increased strength and resistance to corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can withstand temperatures up to 482°F (250°C) and is designed to perform well in harsh sealing environments. The center layer is uncoated stainless steel, allowing for variations in thickness to meet different requirements. These MLS gaskets do not require any additional sealants for installation, making the process more straightforward.

This gasket fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet C10, Camaro, and GMC C1500. It's a solid option for rebuilding or upgrading the top end of your Gen 1 Small Block V8.
