Key Features:

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

• Multi-layer steel construction for enhanced strength and durability
• Embossed outer layers coated with heat-resistant Viton rubber for superior sealing
• Compressed operating thickness of 0.098 inches ensuring optimal gasket crush
• Designed to withstand shearing forces between aluminum heads and cast iron or aluminum blocks
• Corrosion-resistant stainless steel layers for long-lasting performance
• Viton coating rated for heat resistance up to 250°C (482°F)
• Precision bore size of 4.100 inches to match factory specifications
• No sealants required, simplifying installation and reducing potential failure points

Construction & Design:

The gasket features multiple embossed layers of stainless steel, providing exceptional strength and the ability to rebound under thermal cycling and mechanical stress. The outermost layers are coated with Viton, a high-performance fluoroelastomer rubber known for its excellent heat resistance and chemical durability. This coating enhances the gasket’s ability to seal against harsh combustion pressures and varying surface finishes.

The center shim layer is uncoated stainless steel, allowing for precise thickness control and compatibility with different engine block and cylinder head materials. This design effectively manages the differential expansion between aluminum heads and cast iron or aluminum blocks, preventing leaks and maintaining a reliable seal over time.
