Dart applied the airflow technology developed in their championship winning Pro Stock engine program to produce these state-of-the-art heads.

 

Every intake port, every exhaust runner, every valve bowl, and every combustion chamber is 100% CNC machined on special dedicated PRO 1 castings.

Dart PRO 1 CNC heads are professional quality competition cylinder heads.

They sleeve the head bolt columns between the intake ports to maximize the cross-sectional area at a critical point in the flow path.

The high-velocity raised exhaust ports are modeled on their own Pro Stock heads using airflow concepts that dramatically improve cylinder scavenging and the engine’s ability to accelerate quickly.

Multi-angle intake valve seats direct the air-fuel mixture into the chamber like an airfoil, reducing turbulence and preventing fuel separation.

Fully radiused exhaust seats provide the smoothest possible transition into the ports for hot exhaust gases.

Improved cylinder scavenging allows more fuel and air to be burned on the next power stroke.
