Key Features:

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

• Constructed from multiple embossed layers of stainless steel for increased strength and durability
• Outer layers coated with Viton rubber, a heat-resistant elastomer rated up to 250°C (482°F) for superior sealing
• Compressed operating thickness of 0.036" to maintain precise sealing under high pressure
• Embossed outer layers enhance gasket sealing by conforming to surface irregularities
• Center shim layer of uncoated stainless steel allows for thickness customization and reliable compression
• Designed to resist corrosion and withstand shearing forces between dissimilar metals such as aluminum heads and cast iron blocks
• Eliminates the need for additional sealants, simplifying installation and reducing potential failure points
• Specifically engineered for Chrysler 6.1L Gen-3 Hemi engines with a 4.250" bore diameter

Construction & Design:

The Cometic MLS head gasket features a robust multi-layer steel construction that combines strength with flexibility. Each gasket is composed of several layers of stainless steel, with the outermost layers embossed and coated on both sides with Viton rubber. This coating provides excellent resistance to heat, oil, and coolant, ensuring a tight seal even in extreme operating environments.

The embossed design on the outer layers improves the gasket’s ability to conform to the cylinder head and block surfaces, compensating for minor imperfections and enhancing sealing integrity. The uncoated stainless steel center shim provides structural support and can be tailored to specific thickness requirements, allowing for precise engine assembly and optimal compression.
