The hemi head always has intake and exhaust valve stems that point in different directions, requiring a large, wide cylinder head and complex rocker arm geometry in both cam-in-block and single overhead cam engines (dual overhead cam engines may not have rocker arms). This adds to the overall width of the engine, limiting the vehicles in which ...
The Hemi-6 is a pushrod O.H.V. (overhead valve engine), with combustion chambers comprising about 35% of the top of the globe. This creates what is known as a low hemispherical shaped chamber. In this way, the "Hemi" moniker was used for the same kind of marketing cachet as Chrysler's 1950s-1970s Hemi V8 engines.
Cast iron exhaust manifolds, less restrictive than units found on previous engines, were bolted to the outboard side of each head. The new cylinder heads also featured stud-mounted rocker arms, a change from the shaft-mounted LA arms. This last change was due to the different oiling system of the new engine, as described in the next paragraph. [10]

Chrysler's Multi-Displacement System (MDS) is an automobile engine variable displacement technology. It debuted in 2005 on the 5.7 L modern Hemi V8.Like Mercedes-Benz's Active Cylinder Control, General Motors' Active Fuel Management, and Honda's Variable Cylinder Management, it deactivates four of the V8's cylinders when the throttle is closed or at steady speeds.
The Ram Air IV used the Ram Air II's camshaft but lift in the Ram Air IV was increased to 0.52 in (13 mm) thanks to the use of 1.65 ratio rocker arms (vs 1.50). The Ram Air IV heads had 1/8" taller intake ports, larger intake port volume with more airflow, yet shared the Ram Air II round exhaust ports.
