Cometic Top End Gasket Kit, 54 mm, Honda (C7181)

The Cometic C7181 Top End Gasket Kit is designed for Honda 4-stroke engines requiring dependable sealing during top-end service or rebuilds. This comprehensive kit includes the correct base gasket, head gasket, cylinder O-rings, rocker gasket, and other application-specific O-rings or seals needed for top-end removal and reassembly. Supplied components help simplify installation while supporting consistent sealing across critical engine surfaces.
The multi-layer steel (MLS) head gasket promotes even torque distribution across the gasket sealing surface, helping reduce bore distortion and support an improved piston ring seal. Cometic’s 4-stroke head gasket construction is engineered for today’s high-output naturally aspirated and boosted machines, using embossed outer steel layers with a durable Viton rubber coating. This design helps the gasket withstand high horsepower and cylinder pressure while maintaining reliable performance.
Cometic Extreme Sealing Technology (EST) combines embossed stainless steel head, base, and rocker gaskets with a proprietary rubber coating. The head gasket material helps draw heat away from the combustion ring and distribute it evenly across the gasket surface, reducing hot spots and helping prevent gasket failure. The result is a dependable sealing solution for demanding Honda applications and professional-quality engine service.
Made in the USA, the Cometic C7181 Top End Gasket Kit provides application-focused components and advanced gasket construction for a precise, durable top-end repair. Verify engine fitment before installation and follow the manufacturer’s recommended torque sequence and service procedures.
