Cometic Chevy Gen-1 Small Block V8 .089in MLS Cylinder Head Gasket - 4.100in Bore - Round Bore

What you get here is a Cometic Multi-Layer Steel (MLS) cylinder head gasket designed for Chevy Gen-1 Small Block V8 engines. This gasket has a 4.100 inch bore and is 0.089 inches thick, with a round bore opening. It's built with multiple layers of stainless steel, which gives it strength and helps it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle high temperatures up to 482 degrees Fahrenheit, making it suitable for demanding sealing environments.

These MLS gaskets are a solid choice for modern, high-output engines because they seal well without needing any extra sealants. They work great whether you're mating aluminum heads to an aluminum block or aluminum heads to a cast iron block, as they can handle the different expansion rates between those materials. The center layer is stainless steel and can be varied in thickness to meet different engine build requirements, with this particular gasket set to a compressed thickness of 0.036 inches.

This gasket fits a wide range of vehicles from the early 1980s through the mid-1990s, including many Chevrolet and GMC trucks and cars like the Camaro, Corvette, and C/K series trucks. It's a well-built component that's ready to go right out of the box for your engine rebuild.
