Pro 1 CNC Series Cylinder Head Information

CC Size Bare Cylinder Head Price Complete Cylinder Heads
335cc $1383.71 each From $1809.90 each
355cc $1383.71 each From $1809.90 each

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. Cylinder head bolt columns have sleeves between the intake ports to maximize the cross-sectional area at a critical point in the flow path. There are two choices of intake ports; 335cc and 355cc so you can match the runner volume to your engine's displacement and rpm range. 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.
