About This Product
This Cometic EST top end gasket kit is the perfect choice for refreshing 1984 to 1991 Evolution Big Twin engines. It features 3.5-inch bore Multi-Layer Steel (MLS) head gaskets at 0.030-inch thickness, paired with 0.020-inch Single-Layer Steel (SLS) cylinder base and rocker cover gaskets. These SLS gaskets are coated with high-temperature Viton rubber for a superior seal that resists leaks and heat degradation. The kit includes all the gaskets, seals, and O-rings required for a complete top-end rebuild, ensuring your Evolution engine stays dry and maintains peak compression. This high-quality gasket kit is sold as a set.
