Each Cylinder head is accurately modified, firstly by CNC Milling machine to ensure consistency, then finished by hand. Each combustion chamber is specially shaped and balanced, each individual port is then gas flowed and finally the inlet ports are highly polished by hand to produce a consistently accurate modified product, guaranteeing the maximum percentage increase in air flow, so therefore increasing BHP and torque.
