Cometic Chevy Gen-1 Small Block V8 4.200in Bore 18/23 Degree Head .051in MLS Cylinder Head Gasket

Cometic Gasket is a well-known name for its multi-layer steel (MLS) head gaskets, and this C5249-051 is built to handle the demands of high-output engines. It's designed for Chevy Gen-1 Small Block V8 applications, featuring a 4.200-inch bore and a 0.051-inch compressed thickness. This gasket is suitable for a wide range of vehicles, including models like the Chevrolet C10, Camaro, and GMC C1500, making it a versatile choice for many rebuilds.

This MLS gasket is constructed from multiple layers of stainless steel, which gives it increased strength and resistance to corrosion. The outer layers are embossed and coated with Viton, a heat-resistant rubber material that can handle harsh sealing environments and various surface finishes up to 482 degrees Fahrenheit. The center layer is uncoated stainless steel and can be varied to achieve different thicknesses. Because it's an MLS gasket, it doesn't require any sealants and is ideal for use with both aluminum and cast iron blocks and heads, as it can withstand the shearing forces that can occur between different metals.
