Cometic Chevy Gen1 Small Block V8 .030in MLS Cylinder Head Gasket - 4.060in Bore - Vortec Heads

If you're rebuilding the top end of your Chevy Gen-1 Small Block V8, this Cometic Multi-Layer Steel (MLS) cylinder head gasket is a solid choice. It's specifically made for Vortec heads and comes in a .030 inch oversize to match a 4.060 inch bore, which is common when engines have been previously machined or for performance builds. This gasket fits a wide range of vehicles, including popular models like the Chevrolet C10, Camaro, and GMC C1500 from the 1980s.

Cometic builds these gaskets with three to five layers of stainless steel. They use stainless steel because it's strong, resists corrosion, and can rebound well under pressure. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This coating helps ensure a good seal even in tough operating conditions and on various surface finishes.
