Looking for horsepower? Super Port Flow will give it to you. In fact, professional porting is the most important performance modification you can make to your Harley Davidson.

Super Port Flow, available only from FLO Headworks, is a special process we carry out on your Harley’s cylinder heads. Incorporating unique carbide cutters from R&R Specialties, we combine our advanced flow bench techniques with our patented Tooled Finish. As independent flow charts and dyno testing have proven, the result is dramatically increased real-world power.

Apart from the porting services we are famous for, we can carry out a full range of cylinder head and top end machining services for your Harley-Davidson, whatever its engine type. Our 25 years of experience means the job gets done right the first time.
