       Title Page:

       A similar choke point exists on the exhaust side. It also represents the minimum cross section and typically has a larger radius to encourage smooth exhaust flow, which exits under high pressure.

       The throat area immediately above the valveseat is the controlling factor in airflow efficiency. Maximum velocity across the valve should be generated here.

       Top Right:

       Cylinder heads are the most influential component of an internal combustion engine. They are the gatekeeper that regulates the amount and quality of the air/fuel mixture entering the engine.

       Naturally aspirated applications typically require much more flow-bench work to extract maximum performance for each application. Experience pays off, but it still may require long hours of trial and error. (Photo Courtesy Smithberg Racing)

       Modifying port entry angles via specific port matching produces power. The match between the runner exit and the intake port entry should be almost seamless with no sharp edges or area change. Epoxy filling is sometimes required to accomplish the smooth finish. (Photo Courtesy Wilson Manifolds)
