About this part

Product Details

When you're rebuilding the top end of your 6.1L Gen-3 Hemi, you need a head gasket that can handle the heat and pressure. This Cometic MLS (Multi-Layer Steel) head gasket is built for that job, specifically designed for engines with a 4.125-inch bore and an aluminum-sleeved block. It's a .075-inch thick gasket, which is a common thickness for these engines, helping to maintain proper compression ratios.

Cometic builds these gaskets with three to five layers of stainless steel. They use stainless steel because it's strong, can spring back into shape after being compressed, and resists corrosion. The outer layers are embossed and then coated on both sides with Viton, a rubber material that can handle temperatures up to 482°F (250°C). This coating is crucial for sealing well in tough conditions, under heavy loads, and on surfaces that aren't perfectly smooth.
