Cometic Top End Gasket Kit for Honda 91 mm Engines (C7020)

The Cometic C7020 Top End Gasket Kit includes the essential gaskets and seals required for top-end removal and installation on compatible Honda engines. The kit includes the correct base gasket, head gasket, cylinder O-rings, and additional top-end-specific O-rings or seals, providing a convenient solution for engine service and rebuild applications.
The multi-layer steel head gasket is designed to promote even torque distribution across the sealing surface, helping reduce bore distortion and support improved piston ring sealing. Cometic’s 4-stroke head gasket construction is engineered for high-output naturally aspirated and boosted engines, using embossed outer steel layers with a durable Viton rubber coating for reliable sealing under high cylinder pressure.
Cometic EST, or Extreme Sealing Technology, incorporates embossed stainless steel head, base, and rocker gaskets coated with proprietary rubber material. The head gasket material helps transfer heat away from the combustion ring and distribute it evenly across the gasket surface, helping minimize hot spots and reduce the risk of gasket failure. Manufactured in the USA, the Cometic C7020 provides dependable sealing performance for demanding Honda engine applications.
