Key Features

Cometic’s MLS head gasket incorporates advanced materials and engineering to meet the rigorous demands of modern performance engines. Key features include:

• Multi-layer steel construction for superior strength and durability
• Embossed outer layers coated with Viton rubber for enhanced sealing and heat resistance
• Compressed operating thickness of 0.036" for precise fitment and optimal sealing
• Compatible with aluminum heads to aluminum blocks and aluminum heads to cast iron blocks
• Corrosion-resistant stainless steel layers for extended service life
• Designed to withstand shearing forces between dissimilar metals without failure
• No sealants required, simplifying installation and reducing potential leak points
• Center shim layer of uncoated stainless steel tailored to exact thickness specifications
• Heat resistance up to 250°C (482°F) thanks to Viton coating technology

Construction & Design

This head gasket features a sophisticated multi-layer steel design composed of several embossed stainless steel layers. The outer layers are coated on both sides with Viton, a high-performance fluorocarbon elastomer known for its exceptional heat resistance and chemical stability. This ensures a reliable seal even under extreme thermal and mechanical stresses encountered in high-output engines.

The center shim layer is made from uncoated stainless steel, allowing precise control over gasket thickness to meet the specific requirements of the 6.4L 392 HEMI engine. The combination of these materials provides excellent rebound characteristics, corrosion resistance, and the ability to accommodate differential expansion rates between aluminum heads and iron or aluminum blocks, preventing gasket failure and leaks.

Installation & Fitment

The Cometic MLS Head Gasket is designed for direct replacement on 2011–2024 Dodge 6.4L 392 HEMI engines, including those equipped with World Products Man-o-War blocks. Installation follows standard head gasket replacement procedures and requires no additional sealants or adhesives, reducing installation time and complexity. Proper torque specifications and head bolt patterns must be observed to ensure optimal sealing and long-term reliability.
