Key Features

Cometic’s MLS Head Gasket incorporates advanced materials and design features to deliver superior sealing and longevity:

• Multi-Layer Steel (MLS) construction with three to five layers of stainless steel for enhanced strength and durability
• Embossed outer layers to improve sealing under varying load conditions
• Coated on both sides with heat-resistant Viton rubber, capable of withstanding temperatures up to 250°C (482°F)
• Excellent corrosion resistance to extend gasket life in harsh engine environments
• Designed to accommodate a variety of surface finishes and sealing demands
• Precision bore size and thickness to maintain proper engine geometry and compression
• Manufactured to meet or exceed OEM specifications for the Dodge Viper 8.4L V10

Construction & Design

The Cometic MLS Head Gasket is crafted from multiple layers of high-grade stainless steel, which provides exceptional strength and the ability to rebound after compression. This multi-layer design ensures a consistent and reliable seal even under the extreme thermal and mechanical stresses experienced by the Dodge Viper’s V10 engine.

The embossed outer layers enhance the gasket’s sealing capability by creating a controlled deformation that adapts to surface irregularities. Both sides of the gasket are coated with Viton rubber, a synthetic fluoropolymer elastomer known for its outstanding heat resistance and chemical stability. This coating protects the gasket from oil, coolant, and combustion gases, preventing leaks and extending service life.

Installation & Fitment

This MLS head gasket is a direct fit replacement for the 2008–2017 Dodge Viper 8.4L V10 engine. Installation requires removal of the cylinder heads and proper surface preparation to ensure a clean, flat sealing surface. It is critical to follow the manufacturer’s torque specifications and tightening sequence to achieve optimal sealing performance. Purchasing two gaskets is necessary to replace both cylinder heads during a full engine rebuild or repair.
