COMETIC Top End Gasket Kit - Twin Cooled - .040" C10138

A failed head gasket doesn't just sideline your engine—it compromises every system downstream. The COMETIC Top End Gasket Kit eliminates hot spots that cause premature failure by actively dissipating combustion heat across the entire gasket surface, giving you the reliability needed for sustained high-performance driving. This complete kit delivers everything required for a professional top-end rebuild, so you're not hunting down individual components or making a second trip to source missing seals.

Built with EST (Extreme Sealing Technology), this kit pairs embossed stainless steel construction with proprietary rubber facing for superior clamping force and thermal management. Whether you're rebuilding after a failure or refreshing your engine on a planned overhaul, you get a U.S.A.-manufactured solution engineered to handle the demands of forced induction and sustained boost.
