The redesigned chamber features improved fuel distribution, spark plugs are located high and 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.
PRO 1 heads can be used with off-the-shelf pistons, valve train components, and intake manifolds, making them an ideal choice for street/strip to all out competition applications.
