Gen III Hemi 212cc LH Cyl Head 73cc CNC Assem

The Gen III Hemi 212cc LH Cyl Head 73cc CNC Assem from Air Flow Research is a premium upgrade designed for serious Dodge and Chrysler engine builders focused on maximizing combustion efficiency and horsepower. This left-hand cylinder head is specifically engineered for Gen III Hemi platform engines found in popular models such as the Dodge Charger, Challenger, Magnum, and Jeep Grand Cherokee. Whether you're building a street performance engine or aiming for track-focused power, this CNC-ported head provides the necessary flow characteristics for high-rpm breathing and increased boost levels.

The AFR 212cc intake runner design enhances air velocity and optimizes turbulence across the RPM band, while the 73cc combustion chamber volume is precisely machined using CNC technology to ensure consistency and tight tolerances. This chamber size works effectively with modern piston designs to achieve favorable compression ratios in both naturally aspirated and forced-induction applications. The complete assembly arrives ready for installation, eliminating the need to source individual valve train components and ensuring proper valve seat concentricity and port matching to your intake manifold.

Engine builders and performance shops specializing in Hemi power plants rely on this left-hand head for cylinder head swap projects, complete engine rebuilds, and forced-induction calibration work. The LH designation pairs with a matching RH head to create a fully optimized engine setup. This product is an excellent choice for those looking to enhance the performance of their Hemi engines.
