Cometic Chevy Gen-I Small Block V8 .040in MLS Cylinder Head Gasket - 4.200in Bores

When you're rebuilding the top end of your Chevy Gen-I Small Block V8, a solid head gasket is crucial for sealing the combustion chamber. This Cometic MLS (Multi-Layer Steel) head gasket is specifically made for engines with 4.200-inch bores and 18/23 degree cylinder heads, and it's designed without steam holes. It's a well-built component that fits a wide range of vehicles from the early 80s, including popular models like the Chevrolet C10, Camaro, and GMC C1500.

This gasket uses Cometic's HP shim technology, which helps increase the clamping force around the combustion chamber. This is especially beneficial for open deck blocks, helping to ensure a better seal and prevent leaks. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and fluids, further enhancing its sealing capabilities and durability in demanding engine conditions.
