What does the MLX design mean for my engine?

The MLX (Multi-Layer Stopper) design incorporates an integrated stopper layer. This helps provide a better seal around the combustion chamber and improves clamp load without distorting the cylinder head.

Does this gasket require any special sealants?

No, this Cometic MLX head gasket is designed to be installed without the need for additional sealants. It also does not require a re-torque after initial installation.

What is Viton coating and why is it used?

Viton is a high-performance synthetic rubber known for its excellent resistance to heat, oil, and fuel. Coating the gasket with Viton on both sides helps ensure a durable and reliable seal in demanding engine conditions.

About this part

Product Details

If you're rebuilding the top end of your 2010-2014 Ford F-150 with the 6.2L Boss engine, a reliable head gasket is crucial for sealing the combustion chamber. This Cometic MLX head gasket is built to handle the demands of that engine, ensuring a strong seal between the cylinder head and the block.

The MLX (Multi-Layer Stopper) design uses an integrated stopper layer. This helps improve the clamp load around the combustion chamber without causing distortion, which is important for maintaining a consistent seal. It's made from the same durable materials as Cometic's popular MLS head gaskets and comes coated on both sides with Viton, a material known for its resistance to heat and oil. You won't need to use any sealants or re-torque the heads after installation with this gasket.
