Product Details

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, you need a head gasket that can handle the pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built for the job. It's designed to seal tightly between your aluminum or cast iron block and aluminum heads, providing a solid barrier against combustion gases and coolant leaks.

What you get here is a well-built gasket with a compressed operating thickness of 0.077 inches and a bore size of 4.060 inches. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in demanding conditions. This design means you don't need to mess with sealants; the gasket is ready to go right out of the box. It's a popular choice for high-output engines where a dependable seal is critical.

This gasket fits a wide range of vehicles from the early 1980s, including popular models like the Chevrolet C10, Camaro, and GMC C1500. Always refer to the manufacturer's installation instructions for specific details related to your vehicle.
