Cometic Chevy Gen1 Small Block V8 .086in MLS Cylinder Head Gasket - 4.165in Bore - Vortec Heads

Starting with the embossed outer layers coated with Viton, these Cometic Multi-Layer Steel (MLS) head gaskets are built to handle the demands of high-output Chevy Gen1 Small Block V8 engines, especially those using Vortec heads. The Viton coating is a heat-resistant synthetic rubber that can handle temperatures up to 482 degrees Fahrenheit, making it ideal for sealing in tough environments and on various surface finishes. This gasket is designed for a 4.165-inch bore and has a compressed operating thickness of 0.086 inches.

Cometic’s MLS design uses multiple layers of stainless steel, which not only adds strength and resistance to corrosion but also allows the gasket to rebound and maintain a strong seal. This construction is well-suited for applications pairing aluminum heads with either aluminum or cast iron blocks, as it can withstand the shearing forces that can occur between these different materials. Because they are designed for maximum sealing performance, these gaskets typically do not require any additional sealants.

This gasket is a solid option for a wide range of vehicles from the early 1980s, including models like the Chevrolet C10, Camaro, and GMC C1500. It's designed to fit right and perform reliably in these applications.
