Introduction to the technical skills needed to increase the volumetric efficiency of an engine by increasing the size of the head ports and polishing the surface casting. Applications include matching the manifold runners to the head ports, and determining displacement of the combustion chamber. Course work includes using a bench head flow tester to pre-test and post-test the heads. Safety is stressed as well as the proper use of power tools. 2 Credits (1 Lecture - 3 Lab) As needed.
