Cometic Chevy Gen1 Small Block V8 .030in MLS Cylinder Head Gasket - 4.200in Bore

This Cometic Multi-Layer Steel (MLS) head gasket is built with multiple embossed stainless steel layers, featuring Viton rubber coating on the outer surfaces. The compressed operating thickness is precisely 0.030 inches, and it's designed for a 4.200-inch bore, making it a solid choice for Brodix BD2000 heads. These gaskets are well-suited for a wide range of vehicles, including models like the Chevrolet Camaro, GMC C1500, and Buick Century from the early to mid-1980s.

The multi-layer steel construction offers increased strength and resistance to corrosion, while the embossed outer layers coated with Viton provide excellent sealing performance. Viton is a heat-resistant material capable of handling demanding sealing environments and surface finishes, up to 482 degrees Fahrenheit. This design means the gasket requires no additional sealants, simplifying installation and ensuring a reliable seal between aluminum heads and either aluminum or cast iron blocks, effectively handling the shearing forces that can occur between dissimilar metals.
