The CNC machine performs the modifications to the intake, exhaust, bowl area, and-in the case of the 5.3 heads-the combustion chamber, which is opened up to 62.5 cc's. According to Mangum, "The ability to test and develop a head program, then ensure repeatable, high-quality performance is paramount to our business.
