Cometic C8641 MLS Head Gasket 86mm Bore .030 Compressed Thickness

The Cometic C8641 is a high-performance Multi-Layer Steel (MLS) head gasket designed for 86mm bore engines. This premium gasket is engineered to deliver superior sealing performance in demanding high-output applications where traditional composite gaskets fall short.

Key Features:

• 86mm bore diameter with .030 inch compressed thickness
• Multi-Layer Steel construction with multiple layers of stainless steel for maximum strength and durability
• Outer layers feature embossed Viton coating on both sides for superior sealing and corrosion resistance
• Viton coating is heat resistant up to 250°C (482°F)
• Uncoated stainless steel center shim layer provides excellent rebound characteristics
• Ideal for aluminum-to-aluminum and aluminum-to-cast iron block applications
• Withstands extreme cylinder pressures and shearing forces between dissimilar materials
• No sealants required - installs dry on properly prepared surfaces
• No re-torque necessary when correctly installed

Cometic MLS gaskets are designed to meet the demands of harsh sealing environments with varying load conditions and surface finishes. The multi-layer design distributes clamping loads evenly while minimizing bore distortion, resulting in exceptional sealing performance for high-performance and racing applications.
