Remind me what spring you've got? And ya'll had to shim it? stock valves, yes? What are the valve sizes? I forget.

The Eagle Hemi cylinder head arrived in 2009 with VVT on non-SRT Dodge passenger cars and trucks. As with the early head, the Eagle uses rocker shafts and 1.65:1 ratio rockers, but there are big differences in the size and shape of the intake port and the rest of the valvetrain. The Eagle uses 2.05-inch intake and 1.55-inch exhaust valves that are not only larger, they are also longer than standard. The rocker support is taller, and the valve-guide support boss sits higher on the top side of the head, moving it out of the intake port. The Eagle uses a larger square port like the 6.1L that flows a massive 331 cfm right out of the box.
