The Hemi uses two distinct rocker shaft assemblies, both employing a 1.65:1 ratio. The intakes can be identified by the small, cast-in "I" on each rocker (circle). The conical or beehive-shaped valvesprings reduce spring mass by employing a smaller retainer.

This cutaway of the oil circuit reveals the highlighted hydraulic oil pressure circuit that is routed to the hydraulic solenoid in the lifter valley.
