Factory HEMI Head!

The reason I would keep the intake on the left side, is that very high RPM Hemi's benefit from a long, curved runner. The curve helps pile the mixture to one side, and creates a swirl effect in the otherwise dead parts of the chamber. All that room could make for some very interesting intake combinations

Exhaust on left. Intake on right. Intake manifold runners fold over head and end up on left.............
