The AFR BULLITT line of cylinder heads for the Big Block Ford feature a different port shape with a more consistent cross-sectional area and new valve positioning compared to the factory heads. This new clean-sheet design improves engine response, providing increases in horsepower and torque. Available in 280cc, 295cc and 315cc versions with 75cc or 85cc combustion chambers and a .250 raised exhaust port is also available.
