AFR recently released their new big-block Ford Bullitt CNC ported cylinder heads. These new heads feature a different port shape with a more consistent cross-sectional area and new valve positioning compared to the factory pieces. The clean-sheet design improves engine response, providing increases in horsepower and torque. They are now available in 280cc, 295cc and 315cc intake runner versions with either 75cc or 85cc combustion chambers. A raised exhaust port 0.250 is also available.
