Construction & Design

The Cometic MLS cylinder head gasket features a robust multi-layer steel design that balances strength with flexibility. Stainless steel layers provide excellent tensile strength and the ability to rebound after compression, critical for maintaining a tight seal over time. Embossed outer layers increase gasket surface contact, enhancing sealing capabilities.

Both sides of the gasket are coated with Viton rubber, a high-performance elastomer known for its resistance to heat, oil, and chemicals. This coating ensures a secure seal even under the extreme conditions found in high-output engines. The gasket’s .075-inch thickness is optimized for the 5.7L Gen-3 Hemi, ensuring proper compression and fitment without modification.

Installation & Fitment

This gasket is designed as a direct replacement for factory head gaskets on compatible vehicles, fitting the right-hand side (RHS) cylinder head of the 5.7L Gen-3 Hemi engine. Installation is straightforward for experienced mechanics and professional shops, requiring no modifications to the engine block or cylinder head.

Proper installation includes thoroughly cleaning and inspecting the cylinder head and block surfaces to ensure a smooth, flat sealing area. Following factory torque specifications and tightening sequences is essential to guarantee optimal gasket performance and longevity.
