Key Features:

Built with advanced materials and precision engineering, the Cometic MLS Cylinder Head Gasket offers the following benefits:

• Multi-layer steel (MLS) construction with three to five layers for enhanced strength and durability
• Outer layers embossed and coated on both sides with heat-resistant Viton rubber, rated up to 250°C (482°F)
• Exceptional resistance to corrosion and chemical degradation
• Designed to withstand high combustion pressures and thermal cycling without loss of sealing integrity
• Precise bore size of 4.185 inches to match factory specifications
• Thickness of 0.080 inches to maintain proper engine geometry and compression ratio
• Compatible with a variety of surface finishes and load conditions
• Ideal for high-performance and forced induction applications

Construction & Design:

The Cometic MLS gasket features a robust multi-layer steel design, combining three to five layers of stainless steel for superior strength and flexibility. Stainless steel provides excellent rebound characteristics, allowing the gasket to maintain a consistent seal even under extreme thermal expansion and contraction cycles. The outer layers are embossed to enhance sealing capability and coated with a durable Viton rubber compound on both sides. This coating improves the gasket’s ability to seal against surface imperfections and resist harsh chemicals, oils, and coolant exposure.

The Viton material is engineered to withstand temperatures up to 250°C (482°F), making it suitable for high-heat environments typical of performance engines. This advanced construction ensures long-lasting reliability and prevents common gasket failures such as leaks or blowouts.

Installation & Fitment:

This gasket is designed as a direct replacement for factory cylinder head gaskets on the specified Chrysler 6.1L Gen-3 Hemi engines. Installation requires standard head gasket replacement procedures, including proper surface preparation and torque specifications to ensure optimal sealing. No modifications to the engine block or cylinder head are necessary, making it a straightforward upgrade for performance enthusiasts and professional mechanics alike.

Always follow manufacturer torque sequences and use appropriate head bolt replacement if recommended to achieve the best results.
