Dart Race Series 10-Degree LS Cylinder Heads

The most potential to increase performance--Dart Race Series 10-degree LS cylinder heads deliver perfection and power for NMCA Pro Stock. These are the ultimate choice for maximum competition--drag race, naturally aspirated, heavy nitrous, or forced induction applications. Being a radical departure from traditional LS heads, Dart has designed these heads with raised Pro Stock oval ports, canted valves, and highly efficient wedge-style combustion chambers. Also, the intake and exhaust valve locations for each cylinder have been reversed--a feature that has been the standard for maximum power wedge engines for decades. The huge flow resulting from the 10 degree valve angle, splayed valve layout, reversed symmetrical intake ports, and highly efficient combustion chambers deliver maximum power!
