Cometic Chevy Small Block 4.060 inch Bore .140 inch MLS-5 Head Gasket (18 or 23 Deg. Heads)

When you're rebuilding the top end of your Chevy small block, you'll get a pair of Cometic MLS-5 head gaskets in this package. These gaskets are built for a 4.060 inch bore and are designed to work with either 18 or 23-degree cylinder heads, featuring a round bore profile.

Cometic uses a Multi-Layer Steel (MLS) construction for these gaskets, which means they're made of several layers of stainless steel. This design gives them increased strength and the ability to rebound, helping them resist corrosion and handle the stresses of high-output engines. The outer layers are coated with Viton, a heat-resistant rubber material that can handle temperatures up to 482 degrees Fahrenheit, ensuring a solid seal against both aluminum and cast iron blocks without needing any extra sealants. The compressed thickness is set at 0.140 inches.

These gaskets are a popular choice for a wide range of Chevrolet and GMC vehicles from the early 80s, including models like the Chevrolet C10, Camaro, and GMC C1500. They are designed to fit right and provide reliable sealing for your engine build.
