Get a reliable, performance-focused seal for your next top-end service. The Cometic Top End Gasket Kit (C3268-EST) is designed for demanding 4-stroke engines where consistent sealing and durability matter. By using an MLS (multi-layer steel) head gasket design, it helps distribute clamping force evenly across the sealing surface—supporting better piston ring seal, reduced bore distortion and strong long-term performance.
This kit simplifies rebuilds by including the correct base and head gasket, cylinder O-rings, plus additional top-end specific O-rings/seals needed for removal and reinstallation of the top end. The gasket material is engineered to pull heat away from the combustion ring and spread it evenly across the surface, helping reduce hot spots and the risk of gasket failure under high cylinder pressures.
