Cometic C8160 Copper Cylinder Head Gasket 83mm Bore .043" Thickness

The Cometic C8160 is a high-performance copper cylinder head gasket designed for engines with an 83mm bore size and approximately 1428cc displacement. This gasket features a compressed thickness of 0.043 inches (1.09mm), making it ideal for custom compression ratio tuning and performance applications.

Key Features:

• Material: Fully annealed dead soft copper construction for superior conformability
• Bore Size: 83mm for precision fitment
• Compressed Thickness: .043 inches
• Single-layer copper design that easily compresses during installation
• Ideal for engines machined for steel o-rings in extreme cylinder pressure applications
• Provides excellent heat transfer and sealing properties

Cometic copper head gaskets are the preferred choice for high-compression racing engines and performance builds where precise deck height and compression ratio control are critical. The dead soft copper material conforms to irregularities in the head and block surfaces, creating a reliable combustion seal without requiring additional sealants.
