HEAD-M-BUSA-CNC-BV
After extensive development work on the flow bench & engine testing, our latest head has +1mm valves on the inlet & exhaust with bronze guides for added reliability. The ports are CNCd to ensure high accuracy & repeatability. Modifications have been carried out to allow camshafts with over 11mm of lift.

We consider this to be the best head available & when used with our range of components, we have seen the greatest output for normally aspirated hayabusa engines. However, even if you decide to add it to your current tuned engine it should make a significant improvement.
