Cometic Chevrolet 348/409 W-Series Big Block V8 .056in MLS Cylinder Head Gasket - 4.375in Bore

Cometic Gasket is known for making well-built sealing components, and this Multi-Layer Steel (MLS) cylinder head gasket is a prime example. It's designed specifically for Chevrolet 348/409 W-Series Big Block V8 engines, helping to ensure a solid seal between your cylinder head and engine block. This gasket is crucial for maintaining proper compression and preventing coolant and oil leaks, keeping your engine running smoothly.

This gasket is constructed from three to five layers of stainless steel. Cometic chooses stainless steel because it offers increased strength, a good ability to rebound under pressure, and resistance to corrosion. The outer layers of this gasket are embossed and then coated on both sides with Viton, a high-performance rubber material. This coating is designed to handle tough sealing environments and varying load conditions, and it's heat resistant up to 482°F (250°C), making it a reliable choice for these powerful V8s. The .056 inch thickness and 4.375 inch bore are specific dimensions for this application.

This gasket fits a range of classic Chevrolet vehicles, including models like the Bel Air, Impala, and C10 Pickup from the late 1950s and early 1960s. Ensure you have the correct bore size and thickness for your specific engine build.
