Cometic Top End Gasket Set for Big Twin - C9917
High-quality gaskets ensure long-term reliability
Gasket sets feature Extreme Sealing Technology (EST) including embossed stainless steel head, base and rocker gaskets covered with a proprietary rubber material
Head gasket material allows heat to be drawn away from the combustion ring and dissipated evenly across the gasket surface to eliminate hot spots which could lead to gasket failure
Sets contain all the necessary gaskets, seals and O-rings to rebuild the top end from the cylinder base up

NOTE: For S&S Big Twin with S&S rocker box gaskets, 4.00 in. bore
