Key Features:

Built for durability and precision, the Cometic MLS Head Gasket offers the following benefits:

• Multi-Layer Steel (MLS) construction for maximum strength and sealing integrity
• Embossed outer layers coated with Viton rubber for superior heat and chemical resistance
• Compressed operating thickness of 0.036 inches to maintain optimal sealing under pressure
• Designed to withstand the shearing forces between aluminum heads and cast iron or aluminum blocks
• Corrosion-resistant stainless steel layers that rebound to maintain a tight seal over time
• No sealants required, simplifying installation and ensuring consistent performance
• Precision bore size of 4.100 inches to match factory cylinder dimensions
• Compatible with World Products Man-o-War engine blocks
• Heat resistance up to 250°C (482°F) thanks to Viton coating

Construction & Design:

This head gasket features a sophisticated multi-layer steel design, combining multiple embossed stainless steel layers for enhanced strength and flexibility. The outer layers are coated on both sides with Viton, a high-performance fluoroelastomer rubber known for its exceptional heat resistance and durability in harsh sealing environments. The center shim layer is uncoated stainless steel, allowing for precise thickness adjustments to meet specific engine requirements.

The gasket’s design accommodates the differing expansion rates of aluminum heads and cast iron or aluminum blocks, preventing leaks caused by thermal cycling and mechanical stress. Its corrosion-resistant materials ensure long-lasting reliability, even in high-temperature and high-pressure conditions typical of modern HEMI engines.
