Cometic Chevrolet Gen-3 Inline 6 .040in MLS Cylinder Head Gasket - 4.125in Bore

When you're rebuilding the top end of your Chevrolet Gen-3 Inline 6, a solid head gasket is crucial for sealing the combustion chamber and coolant passages. This Multi-Layer Steel (MLS) gasket from Cometic is built to handle the pressures of performance engines, offering a reliable seal without needing extra sealants.

This gasket features multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and varying surface finishes. The center layer is uncoated stainless steel, and this particular gasket has a compressed thickness of 0.040 inches with a 4.125-inch bore, making it suitable for a wide range of Chevrolet Gen-3 Inline 6 applications, including many Buick, Checker, and Chevrolet models from the 1960s and 70s. It's designed to work well with both aluminum and cast iron blocks and heads.
