Description
If you’re running a smaller displacement engine and leaving performance on the table, the S&S Cycle Performance Replacement Head 106-6064 delivers measurable gains in flow and compression without compromise. This fully assembled, U.S.-made head is engineered specifically for efficient smaller motors, giving you the horsepower boost that comes from optimized port design and factory-quality construction. When every tenth of a second counts, precision-built components like this separate winners from the rest.
The head arrives ready to bolt on, complete with stainless steel valves and high-lift springs tuned for .585″ maximum valve lift. Port geometry maintains velocity while increasing flow—a critical balance that delivers usable power across the RPM range rather than peak-number bragging rights. EFI compatibility means this integrates seamlessly into modern fuel management systems.
