What makes AFR Cylinder Heads special?

While Airflow Research (AFR) has a great history of success in racing, it has been AFR's ability to bring sophisticated CNC porting technology to their wide assortment of AFR cylinder heads that makes them truly special. Airflow Research pioneered the tooling and machinery necessary for true 5-axis CNC port machining, which allows airflow consistency from head to head once the port devlopment is complete. AFR is the pioneer manufacture for economical CNC ported cylinder heads.
