from carpenterracing Cylinder head ports fall into two basic designs: the Straight Shot port and the High Approach port. In a Straight Shot port, the design allows for a line of sight from the inlet directly to the front opening of the intake valve. Sometimes this design gives a lower flow value but because it is straight, we attain higher velocity of fuel/air entering chamber.
