What is the advantage of using a multi-layer steel (MLS) gasket?

MLS gaskets offer superior strength and sealing capabilities compared to traditional composite gaskets. The multiple layers of stainless steel allow for better rebound under pressure and resist corrosion, ensuring a more durable and reliable seal for your engine.

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

Viton is a high-performance synthetic rubber known for its excellent resistance to heat and harsh chemicals. On this gasket, the Viton coating helps create a tight seal against the cylinder head and block, even under extreme temperatures and pressures, and accommodates minor surface imperfections.

What does the .066in thickness and 4.250in bore specification mean for my engine?

The .066-inch thickness refers to the compressed gasket height, which is important for maintaining the correct compression ratio. The 4.250-inch bore specification ensures the gasket properly covers the cylinder bore of your specific Gen-2 Hemi engine, preventing leaks between the cylinder and coolant/oil passages.

About this part

Product Details

This Cometic head gasket uses a multi-layer steel (MLS) construction, featuring three to five layers of stainless steel. Stainless steel is chosen for its strength, ability to rebound under pressure, and resistance to corrosion, which is crucial for a long-lasting seal in the demanding environment of an engine's combustion chamber. The outer layers are embossed and coated on both sides with Viton, a heat-resistant rubber material rated up to 482°F (250°C), designed to handle harsh sealing conditions and varying surface finishes found on Gen-2 Hemi engines.

This gasket is specifically designed for a 4.250-inch bore and a .066-inch thickness, making it a well-built option for rebuilding or repairing a wide range of Chrysler Gen-2 Hemi engines. It fits popular models like the Dodge Challenger, Dodge Charger, and Plymouth Barracuda from the late 1960s and early 1970s. The Viton coating helps ensure a tight seal even with imperfect mating surfaces, contributing to improved engine performance and reliability.
