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

The AIR FLOW RESEARCH Gen III Hemi 212cc Right-Hand Cylinder Head with 73cc CNC assembled chambers is designed for Mopar enthusiasts looking to enhance the performance of their modern Hemi engine platforms. This high-performance casting is engineered for Gen III Hemi blocks found in fifth-generation Dodge Chargers, Challengers, Magnums, and Jeep Grand Cherokees, as well as contemporary truck and SUV applications.

With a CNC-machined 212cc intake port volume, this cylinder head optimizes airflow for improved mid-range and peak horsepower gains. The 73cc combustion chamber volume is designed to increase the compression ratio when paired with factory 0.040-overbore pistons, allowing for higher boost levels or naturally aspirated tuning strategies while minimizing the risk of detonation. The investment-cast ductile iron construction ensures durability and longevity under high RPM operation.

This AFR cylinder head is ideal for those building stroker packages or forced induction setups, providing excellent compatibility with OEM or aftermarket exhaust manifolds. While the assembly arrives pre-assembled, proper valve lapping and deck surface verification are recommended for optimal performance. This product is a perfect choice for enthusiasts seeking to transform their stock Hemi into a true performance powerhouse.
