The Hemi-6 valves are angled apart (splayed) 18 degrees (included angle) along the crankshaft axis, and the intake valves are as large as . The 6 intake and 6 exhaust valves open slightly towards each other and away from the cylinder wall, which results in less "shrouding" of the valves and greater airflow potential. In addition, both valves are slightly inclined across the crankshaft axis, similar to a conventional "wedge" chamber. The cylinder head is not a crossflow design, meaning the 6 intake and 6 exhaust ports are on the same side of the engine (the left, Australian and British passenger, side).
