Cometic C9799 HD Shovelhead Stock Bore Head Gasket Set .043" MLS 1966-1983

The Cometic C9799 is a premium Multi-Layer Steel (MLS) head gasket set designed specifically for Harley-Davidson Shovelhead engines from 1966 to 1983. This high-performance gasket kit features stock bore sizing with a .043-inch compressed thickness and includes fire ring technology for superior sealing and combustion chamber integrity.

Key Features:

• Multi-Layer Steel (MLS) construction with CFM-20 coating for maximum durability and heat resistance
• Integrated fire ring design provides enhanced sealing around combustion chambers
• .043-inch compressed gasket thickness for stock compression ratios
• Stock bore sizing for OEM cylinder dimensions
• Includes 2 head gaskets (one pair) for complete engine rebuild
• Application-specific design for 1966-1983 Harley-Davidson Shovelhead engines

Cometic gaskets are engineered to withstand extreme temperatures and pressures, making them ideal for both stock restorations and performance applications. The MLS construction allows the gasket to recover and maintain seal integrity through repeated heat cycles, while the fire ring technology prevents head gasket failure at the most critical sealing points.
