Do I need to use any sealant with this head gasket?

About this part

Product Details

When you're rebuilding the top end of your Chevy Small Block V8, you need a head gasket that can handle the pressure. This Multi-Layer Steel (MLS) gasket from Cometic is built for high-output engines and fits a wide range of vehicles from 1980-1986, including popular models like the Chevrolet C10 and Camaro, as well as GMC C1500 trucks.

This gasket is constructed from multiple layers of stainless steel, which gives it strength and the ability to rebound, helping it resist corrosion. The outer layers are coated with Viton, a heat-resistant rubber material that can handle tough sealing environments and various surface finishes. The compressed thickness is .036 inches, and it has all the steam holes you need for proper cooling. Because it's an MLS gasket, it doesn't require any additional sealants, making installation more straightforward, and it works well with both aluminum and cast iron blocks.
