Why Choose our Stage 4 Head Package Over the Competition? All machining, cleaning, and assembling are done by a degreed engineer. We provide a level of artisan craft in our engines only found in race teams and super cars. The experience we bring to our engine program is unparalleled in the industry. We blueprint the entire assembly of the motor to within .0002 of our specs. It is incredibly important to balance your motor to increase the life of your bearings. It is highly recommended to run a Fluidampr/ATI crank pulley or OEM. Do not run an aftermarket solid crank pulley. All of our inspection equipment is high quality, either from Starrett or Mitutoyo, and is sent off yearly for calibration to a qualified cal-lab.
