About this part

Product Details

When you're rebuilding the top end of your GM LT1 or LT4 Gen-2 small block V8, you need head gaskets that can handle the pressure. This Cometic Multi-Layer Steel (MLS) head gasket is built for that job. It's designed to fit engines with a 4.040 inch bore and has a compressed thickness of .051 inches, with valve pockets to ensure proper clearance.

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 material that can handle temperatures up to 482 degrees Fahrenheit. This coating helps create a strong seal without needing any extra sealants, and it's tough enough to work with both aluminum and cast iron blocks, even when paired with aluminum heads. The multiple steel layers give it strength and the ability to rebound, while also resisting corrosion.

This gasket is a solid option for a range of GM vehicles from the mid-90s, including models like the Chevrolet Corvette, Camaro, and Pontiac Firebird. It's designed to provide reliable sealing for high-output engines.
