We have gained considerable experience in the art of increasing horsepower by careful modifications to Ports, Valves and Seats. This was only possible by extensive use of our Superflow 110 Flowbench, incorporating Flowcom and Computer Software, we know exactly what works, where to remove material, and what the ideal port shape should be. Also with the latest Valve Seat Cutting Machine, we can cut 5 Angle Seats which flow best. We can also Swirl polish and Back Cut valves, modify combustion chambers and set compression ratios. We have experience in Race Rally Fast Road and Track Day modified Cylinder Heads.
