Powerflow Heads are shaped and honed. The heads are put through APL's exclusive Directional Honing Process, maximising flow. Seats are diamond cut and finished heads are fully prepped and re-assembled. Due to its blueprint finish, Powerflow Heads offer improved reliability and longevity.

Powerflow Heads remove the inaccuracy of hand porting and are used by factory MX & off-road race teams. Powerflow porting work is available for Honda, Husqvarna, KTM, Kawasaki, Suzuki and Yamaha engines.
