About this part

Product Details

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a Chevy Gen-1 Small Block V8 engine with a 4.125-inch bore, this gasket is designed to provide a strong seal. It's built with multiple layers of stainless steel, which gives it the strength to handle the demands of high-output engines and helps prevent corrosion.

The outer layers of this gasket are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating, along with the embossed outer layers, helps ensure a reliable seal without needing any additional sealants, whether you're mating aluminum heads to aluminum blocks or aluminum heads to cast iron blocks. The compressed thickness is 0.060 inches, and it includes all the necessary steam holes to help manage heat.

This gasket fits a wide range of vehicles from the early 1980s, including models like the Chevrolet Camaro, GMC C1500, and Buick Century. It's a solid option for rebuilding or repairing your engine's top end.
