Gen III Hemi 185cc RH Cyl Head 69cc Assembled

The AIR FLOW RESEARCH Gen III Hemi 185cc Right-Hand Cylinder Head with 69cc Chamber (AFR 2510) is a precision-engineered, fully assembled aluminum cylinder head purpose-built for high-performance Mopar Gen III Hemi engine applications. This passenger-side head combines a 185 cubic centimeter intake runner with a compact 69 cubic centimeter combustion chamber to deliver optimized flow characteristics and efficient scavenging for serious street and competition builds.

The 2.050-inch intake and 1.590-inch exhaust valves are engineered to maximize volumetric efficiency across the RPM range, while the 1.290-inch valve springs provide controlled lift and precise valve timing without float. The straight-plug configuration simplifies installation and reduces complications with ignition system clearance on modified engine bays. Cast aluminum construction balances durability with thermal management, critical for sustained high-output operation where head temperatures can exceed typical street engine parameters. As a pre-assembled unit, this head arrives ready for installation, eliminating the time and potential for assembly errors associated with component assembly in the field.

This cylinder head is designed for Gen III Hemi engine builders prioritizing intake flow and combustion efficiency for performance applications—whether bracket racing, street performance, or engine dynamometer work. The 185cc intake runner size strikes a balance between flow rate and velocity, favoring mid-to-high RPM power development. Buyers undertaking a complete Hemi rebuild or upgrading from stock castings require a matched pair (one right-hand, one left-hand head); this RH unit pairs with an AFR left-hand equivalent for symmetrical cylinder head performance.

AIR FLOW RESEARCH's reputation in the performance engine market rests on flow-bench validation and dyno-proven results. The AFR 2510 reflects that engineering rigor—every port and chamber dimension is calculated to support efficient combustion and minimal resistance during the intake and exhaust strokes. When precision cylinder head performance and documentation matter, AFR heads deliver the technical foundation serious builders depend on.
