Dart's proprietary "Speed-Flow" Technology has now
produced an affordable LS style cylinder heads with awesome flow and power.
Stock valve angles and centers, drilled and tapped accessory holes and stock
port locations mean you can use stock components. Compact, highly
efficient combustion chambers improve airflow and flame propagation for
increased power and torque. Added material at the top allows flexibility
for upgraded valve train components. Two intake port sizes cover
applications from street cars and trucks to racing. Our race-proven port
designs and advanced casting techniques produce the as-cast ports which flow
like they've been ported, without the time and expense of CNC or hand porting.
