These performance replacement cylinder heads are designed for Evolution Big Twin engines from 1984 to 1999. Optimized for smaller displacement engines, they feature a chamber designed for stock-style, flat-topped pistons. The port design increases airflow while maintaining velocity, and they are set up for a maximum lift of .585". EFI compatible, they have an 82cc chamber, providing an 8.8:1 compression ratio in an 80" motor and 9.5:1 in a 96" motor. They use stock intake manifolds and feature 1.90" intake and 1.75" exhaust valves.
