Cometic C8437 Copper Head Gasket 85mm Bore 1340cc .032 Inch

The Cometic C8437 is a premium copper cylinder head gasket engineered for 85mm bore, 1340cc V-twin applications. Constructed from 99.9% pure oxygen-free C110 copper, this gasket delivers exceptional thermal conductivity and superior sealing performance in high-performance and custom engine builds.

Key Features:

• Made from premium oxygen-free copper for excellent heat transfer and conformability
• Compressed thickness of .032 inch for precise deck height control
• 85mm bore size designed for 1340cc engine displacement
• Compatible with applications using dowel pin alignment
• Ideal for modified engines requiring custom compression ratios
• O-ringing recommended for maximum sealing performance

Cometic copper gaskets are precision-manufactured to strict tolerances and are particularly well-suited for custom engine builds where deck height adjustments and compression ratio tuning are critical. The soft, malleable nature of copper allows the gasket to conform to minor surface imperfections while maintaining a reliable seal under extreme cylinder pressures and temperatures.
