Description
Dart’s highly popular small block Pro 1 heads have been given the full Platinum treatment utilizing wet flow technology. Independent tests have demonstrated an average 25 Horsepower gain over the previous Pro 1 design. The redesigned chamber features improved fuel distribution, spark plugs are located high and as close to the center of the chamber as possible and five angle intake seats shear the liquid fuel and air as it enters the chamber. The intake face, exhaust face and exhaust ports have been redesigned, valve guide bosses are profiled and casting walls are cleaner and more consistent, resulting in greater control over flow, heat and combustion. Four intake runner sizes are available (180, 200, 215 and 230 Cubic Centimeter) to suit engines from mild street to big Inch full competition
