About this part

Product Details

Cometic Gasket has a reputation for making well-built engine sealing components, and this Multi-Layer Steel (MLS) head gasket is a prime example. If you're working on a Chevrolet Gen-1 Small Block V8, especially one with Vortec heads and a 4.165-inch bore, this gasket is designed to provide a solid seal. It's built to handle the demands of higher output engines, meaning it can stand up to more pressure and heat than a standard gasket.

What makes this gasket stand out is its construction. It's made from multiple layers of stainless steel, which gives it a lot of strength and helps it resist corrosion. The outer layers are coated on both sides with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit. This coating is key for sealing effectively against different block and head materials, like aluminum to cast iron, and it means you don't need to use any extra sealants. The center layer is stainless steel and can be varied to achieve different compressed thicknesses, like the 0.036-inch operating thickness of this particular gasket.

This gasket fits a wide range of vehicles, including models like the Chevrolet C10, Camaro, and GMC C1500 from the 1980s. It's a solid option for rebuilding or upgrading your engine, ensuring a reliable seal for your Vortec heads.
