Cometic Chevy Gen1 Small Block V8 .042in MLS Cylinder Head Gasket - 4.125in Bore - 18/23 Degree Head

Starting with the embossed outer layers coated with Viton, this Cometic Multi-Layer Steel (MLS) head gasket is built to handle the demands of high-output engines. The Viton coating is a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, making it suitable for a wide range of sealing environments and surface finishes. This gasket is designed for Chevrolet Gen 1 Small Block V8 engines with a 4.125-inch bore and 18/23-degree cylinder heads.

Cometic's MLS gaskets are constructed from multiple layers of stainless steel, which gives them increased strength and the ability to rebound, helping to resist corrosion. Because they are made of multiple stainless steel layers, they can also handle the shearing forces that can occur between aluminum heads and cast iron blocks. The center shim layer is stainless steel and can be varied to achieve different thicknesses; this particular gasket has a compressed operating thickness of 0.036 inches and an uncompressed thickness of 0.042 inches. These gaskets don't require any additional sealants, simplifying installation.

This gasket fits a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and GMC C1500. It's a solid option when you need reliable sealing for your engine build.
