What is the benefit of Multi-Layer Steel (MLS) construction?

MLS construction uses multiple layers of stainless steel, which increases the gasket's strength and resistance to corrosion. This design also allows the gasket to rebound effectively, maintaining a strong seal under demanding conditions.

Do I need to use sealant with this head gasket?

No, this Cometic MLS head gasket is designed to provide maximum sealing performance on its own and does not require additional sealants. The Viton coating on the outer layers ensures a reliable seal against the engine block and cylinder head.

What is Viton and why is it used on this gasket?

Viton is a heat-resistant rubber material that can withstand temperatures up to 482 degrees Fahrenheit. It's used on the outer layers of this gasket to ensure a durable and reliable seal in the harsh environment of a high-output engine.

Product Details

This Cometic Multi-Layer Steel (MLS) head gasket features a 4.280-inch bore and a compressed thickness of 0.098 inches, making it a solid choice for rebuilding or upgrading Chrysler Gen-2 Hemi engines. These gaskets are built to handle the demands of high-output applications, offering a robust seal without the need for additional sealants. They are designed to work effectively with both aluminum and cast iron blocks, resisting the shearing forces that can occur between different metal types.

The construction uses multiple layers of stainless steel for increased strength and corrosion resistance. The outer layers are coated with Viton, a heat-resistant rubber material capable of withstanding temperatures up to 482 degrees Fahrenheit, ensuring a reliable seal even in harsh conditions. The center layer is also stainless steel and can be varied in thickness to meet specific build requirements. This well-built gasket is suitable for a range of classic Mopar vehicles, including models like the Dodge Charger, Plymouth Barracuda, and Dodge Challenger from the late 60s and early 70s.
