Gen III Hemi 224cc LH Cyl Head 69cc CNC Assem

The Gen III Hemi 224cc LH Cylinder Head by AIR FLOW RESEARCH is a precision-engineered casting designed for serious Dodge and Jeep performance builders targeting high-flow heads without factory limitations. This left-hand cylinder head serves the demanding needs of engine builders, tuners, and enthusiasts who require maximum airflow efficiency and port velocity for naturally aspirated or forced-induction Gen III Hemi platforms.

The 224cc intake runner volume is engineered to balance mid-range torque with high-rpm breathing capability, while the 69cc combustion chamber is CNC-machined to exacting tolerances for repeatable power delivery and compression consistency across applications. AIR FLOW RESEARCH's proven porting geometry, developed through extensive flow-bench testing, optimizes intake and exhaust gas dynamics to extract maximum power per cubic inch.

This head is ideal for Gen III and Gen IV Hemi engine builders working with 5.7L and 6.1L platforms in street, strip, and track applications where standard OEM capabilities are insufficient. The fully assembled configuration eliminates guesswork during installation, with precision valve seats, hardened valve guides, and factory-fresh valve train components ready for immediate engine assembly.
