Cometic C8679 MLS Head Gasket .030" XV1700 Engine

The Cometic C8679 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed for Yamaha XV1700 V-twin engines. This precision-engineered gasket features a .030" compressed thickness, making it ideal for high-compression engine builds.

Key Features:

• Multi-layer stainless steel construction for superior strength and durability
• .030" compressed thickness for increased compression ratio
• Viton rubber coating on outer layers provides excellent heat resistance up to 482°F
• Load-controlled embossments distribute clamping force evenly across sealing surfaces
• Requires no additional sealants when installed on properly prepared surfaces
• Resistant to corrosion with excellent rebound characteristics
• Designed for use with Yamaha XV1700 engines

Cometic MLS gaskets are engineered to handle the thermal expansion and shearing forces in high-performance applications. The stainless steel construction provides exceptional durability, while the integrated Viton coating eliminates the need for aftermarket sealants. For optimal sealing performance, surfaces should be machined to 50 RA or smoother finish.
