Cometic C8677 MLS Cylinder Head Gasket .030" Yamaha XV1700

The Cometic C8677 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed for Yamaha XV1700 V-twin engines. This precision-engineered gasket features a compressed thickness of .030 inches, making it ideal for high-compression engine builds and performance applications.

Key Features:

• Multi-Layer Steel construction with three layers of stainless steel for superior strength and durability
• .030 inch compressed thickness for increased compression ratio
• Outer layers are embossed and coated with Viton rubber for exceptional sealing in harsh environments
• Heat resistant to 482°F (250°C) for reliable performance under extreme conditions
• Load-controlled embossments provide even torque distribution and reduced bore distortion
• No sealants required when properly installed on prepared surfaces
• No re-torque necessary after installation

Cometic MLS gaskets are engineered to withstand the shearing forces created in the cylinder head environment and provide maximum sealing performance for high-output engines. The stainless steel construction offers increased strength, superior rebound characteristics, and excellent corrosion resistance compared to traditional gasket materials.
