Mechanical Roller Drag Race Only

Our largest 20* offering designed for high lift drag racing applications. These heads offer huge horsepower power gains due to their unque design. The High Port® 255 heads feature 255cc intake runners and 68cc CNC-profiled combustion chambers. Designed for 4.125″ bore engines, this 20 degree inline head maximizes high lift flow through the use of a 5 angle intake valve job utilizing a 55* intake seat angle and a 2.125″ titanium valve which optimizes airflow at valve lift above .650″.

Flow sheet provided for your heads.
