Cometic C8070 Copper Head Gasket Thick Bore - 010 1186-1255cc

The Cometic C8070 is a high-performance copper head gasket designed for Harley-Davidson Sportster engines with displacement ranging from 1186cc to 1255cc. Manufactured from 99.9% pure C110 oxygen-free copper, this gasket delivers exceptional sealing performance in high-compression and high-boost applications.

Key Features:

• .010" (0.010 inch) compressed thickness for precise compression ratio control
• 99.9% pure oxygen-free copper (C110) construction for superior thermal conductivity
• Excellent corrosion resistance and ductility
• Not susceptible to embrittlement when exposed to extreme heat
• Compatible with o-ring sealing systems (o-ringing recommended for optimal performance)
• Ideal for custom engine builds and performance applications

Cometic copper gaskets are precision-tested for uniform flatness to ensure an optimal seal between the cylinder head and engine block. This gasket is particularly well-suited for high-performance Sportster builds where reliability under extreme conditions is essential. For best results, ensure block and head surfaces are properly machined and consider using with ARP head studs.
