Cometic Chevrolet 348/409 W-Series Big Block V8 .080in 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 specifically made for Chevrolet 348/409 W-Series Big Block V8 engines and features a 4.375-inch bore with a thickness of .080 inches. This gasket is designed to handle the demands of these classic V8s, ensuring a solid seal between your cylinder heads and engine block.

This gasket is constructed from three to five layers of stainless steel. Cometic chooses stainless steel for its strength, its ability to rebound under pressure, and its resistance to corrosion. The outer layers are embossed and then coated on both sides with a Viton rubber material. Viton is known for its heat resistance, handling temperatures up to 482°F (250°C), which is crucial for keeping a seal in harsh engine environments and under various load conditions. This construction helps it adapt to different surface finishes on your block and heads.

This gasket fits a range of classic Chevrolet vehicles, including models like the Impala, Bel Air, and C10 Pickup from the late 1950s and early 1960s. It's a solid option for anyone rebuilding or restoring these iconic engines.
