Cometic C8165 Copper Head Gasket Bore Thickness - 76mm 1197cc 043

The Cometic C8165 is a precision-engineered copper head gasket designed for high-performance engines with a 76mm cylinder bore and 1197cc displacement. This gasket features a .043-inch (1.09mm) compressed thickness, making it ideal for custom compression ratio tuning and race applications.

Key Features:

• 76mm bore diameter for precise cylinder sealing
• .043-inch compressed thickness for compression control
• Pure copper construction for superior thermal conductivity and conformability
• Designed for 1197cc displacement engines
• Excellent for high-boost and high-compression builds
• Reusable with proper surface preparation and annealing

Cometic copper head gaskets are known for their ability to conform to imperfect sealing surfaces and withstand extreme cylinder pressures. The pure copper material provides excellent heat transfer properties, helping to prevent hot spots and detonation in demanding performance applications. This gasket requires proper surface preparation and the use of appropriate sealant for optimal performance.
