Key Features

Cometic’s MLS Head Gasket incorporates advanced materials and design features to meet the rigorous demands of modern engines:

• Multi-layer steel construction for enhanced strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
• Compressed operating thickness of 0.051" for precise fitment and performance
• Designed to handle the shearing forces between aluminum heads and iron blocks
• Corrosion-resistant stainless steel layers extend gasket life
• Viton coating withstands temperatures up to 250°C (482°F)
• Center shim layer uncoated for customizable thickness options
• No sealants required, simplifying installation and reducing potential failure points

Construction & Design

The gasket is constructed from multiple embossed layers of stainless steel, which provide exceptional strength and the ability to rebound under pressure. The outer layers are coated with Viton, a fluorocarbon elastomer known for its excellent heat resistance and chemical durability. This coating ensures a reliable seal even under extreme thermal and mechanical stress.

The center shim layer is made of uncoated stainless steel, allowing for precise thickness adjustments to accommodate specific engine requirements. This multi-layer design effectively manages the differential expansion between aluminum cylinder heads and iron blocks, preventing leaks and maintaining consistent compression.

Installation & Fitment

This MLS head gasket is a direct fit replacement for 2005–2010 Dodge 6.1L HEMI engines with iron blocks. Installation requires standard head gasket replacement procedures and does not necessitate any modifications or additional sealants. Its precise thickness and robust construction ensure a reliable seal, making it suitable for both OEM rebuilds and high-performance engine builds.

What's Included
