Cometic Chevy Small Block 4.165in Bore .027 inch MLS Head Gasket w/ All Steam Holes

Cometic Gasket is a well-known name for creating durable sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example of their work. Designed for Chevrolet Gen-1 Small Block V8 engines, this gasket is built to handle the demands of high-output applications. It features a compressed operating thickness of just .027 inches and a bore size of 4.165 inches, making it suitable for a wide range of these popular V8s, including vehicles like the Chevrolet C10 and Camaro from the 1980s.

What sets this gasket apart is its construction. It's made from multiple layers of stainless steel, which gives it increased strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in harsh conditions. This design means you don't need any additional sealants, and it works well with both aluminum and cast iron blocks, effectively managing the shearing forces that can occur between different metals.
