What is the main advantage of using an MLS head gasket?

Multi-Layer Steel (MLS) head gaskets offer increased strength and better resistance to corrosion compared to traditional composite gaskets. They are designed to handle the higher pressures and temperatures found in performance engines without needing extra sealants.

Can this gasket be used with both aluminum and cast iron engine blocks?

Yes, this MLS gasket is designed to work effectively with both aluminum heads on aluminum blocks and aluminum heads on cast iron blocks. The construction helps manage the stresses between dissimilar materials.

What is Viton and why is it used on the outer layers?

Viton is a heat-resistant synthetic rubber material that can withstand high temperatures, up to 482 degrees Fahrenheit. Coating the outer layers with Viton helps create a reliable seal in demanding engine environments and on various surface finishes.

Product Details
