Cometic Chevy Gen-1 Small Block V8 .086in MLS Cylinder Head Gasket - 4.100in Bore - Round Bore

When you're rebuilding the top end of your Chevy Gen-1 Small Block V8, you need a head gasket that can handle the pressure. This Cometic Multi-Layer Steel (MLS) gasket is built for that job. It's designed to seal tightly between your aluminum or cast iron block and aluminum heads, even with the different expansion rates these materials can create.

What you get here is a well-built gasket made from multiple layers of stainless steel. The outer layers are coated with Viton, a heat-resistant rubber that can handle tough sealing conditions and various surface finishes. This construction means the gasket can rebound and resist corrosion, while the multiple layers provide increased strength. The compressed operating thickness is .086 inches, and it features a 4.100-inch round bore, making it suitable for a wide range of GM Gen 1 Small Block V8 engines with 18/23 degree cylinder heads, including vehicles like the Chevrolet Camaro, Corvette, and GMC C1500.
