The Cometic C9790-HB is a complete head and base gasket kit designed for Harley-Davidson 88ci and 96ci Twin Cam engines with stock 3.750" bore. This comprehensive kit includes premium Multi-Layer Steel (MLS) cylinder head gaskets with .030" compressed thickness, along with cylinder base O-rings for a complete top-end sealing solution.

Multi-Layer Steel Technology:

  • Three-layer MLS construction with embossed stainless steel layers
  • Proprietary high-temperature Viton coating for superior sealing
  • Reduced clamping load requirements minimize bore distortion
  • Active combustion seal on multiple layers for extreme durability
  • Embossments provide micro-seal against head and block surfaces

Kit Specifications:

  • Bore Size: 3.750" (stock bore)
  • Compressed Thickness: .030"
  • Material: Multi-Layer Steel (MLS)
  • Bore Shape: Round
  • Includes cylinder base O-rings

This kit replaces OEM part number 16775-99 and is designed for Twin Cam engines from 1999-2011. The MLS gasket design ensures reliable sealing under high combustion pressures and temperature extremes, making it ideal for both stock and modified applications. All gaskets are manufactured to order using premium materials for long-term reliability.
