About this part

Product Details

Cometic Gasket is well-known for creating durable sealing solutions for performance applications. This Multi-Layer Steel (MLS) head gasket is built for Chevrolet Gen-1 Small Block V8 engines, specifically when using Brodix BD2000 cylinder heads. It features a 4.030-inch bore and a compressed thickness of .027 inches, making it suitable for a wide range of vehicles from the early 80s, including models like the Chevrolet Camaro, Buick Regal, and GMC C1500.

This gasket is constructed from multiple embossed layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482°F (250°C). This design offers excellent sealing performance for high-output engines and can handle the stresses between aluminum heads and cast iron blocks without needing additional sealants. The stainless steel layers provide increased strength and resistance to corrosion, while the center shim layer can be varied to meet different thickness requirements.
