Cometic Chevy Small Block 4.060 inch Bore .089 inch MLS-5 Head Gasket (18 or 23 Deg. Heads)

When you're rebuilding or refreshing a Chevrolet Gen-1 Small Block V8, you'll want a head gasket that can handle the job. This Cometic MLS (Multi-Layer Steel) head gasket is built for engines with a 4.060 inch bore and is designed to work with either 18 or 23-degree cylinder heads. It features a round bore design, which is common for these engines.

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 ensure a solid seal, even with different materials like aluminum heads and cast iron blocks, and it means you don't need to add any extra sealants during installation. The compressed thickness is 0.089 inches, and the multi-layer steel construction gives it strength and resistance to corrosion.

This gasket fits a wide range of Chevrolet and GMC trucks, cars, and SUVs from the early to mid-1980s, as well as some Avanti and Excalibur models. It's a popular choice for high-output engines where reliable sealing is critical.
