Product Details
If you're rebuilding the top end of your Chevrolet Gen-1 Small Block V8, a solid set of head gaskets is crucial for a leak-free seal. This Cometic MLS (Multi-Layer Steel) gasket is designed for that job, featuring a .056 inch thickness and a 4.030 inch bore, making it suitable for a wide range of applications including those with aftermarket heads.
Cometic builds these gaskets with multiple layers of stainless steel. This material choice gives them strength, helps them rebound to maintain a seal, and resists corrosion. The outer layers are treated with a Viton rubber coating on both sides. Viton is known for its heat resistance, handling temperatures up to 482°F, and it works well across different sealing environments and surface finishes. For aftermarket heads, the water ports are intentionally undersized, giving you the flexibility to customize them to your specific setup.
This gasket fits a broad spectrum of vehicles from the early 80s, including models like the Chevrolet Camaro, GMC C1500, and Buick Century. It's a well-built component designed to handle the pressures and temperatures of a V8 engine.
