Actually, only 8 are velocity stacks. The inside ones appear to be going into the opposite bank plenum ... most likely for improved flow, pressure and /or balance. I'm not engineer, so I may be completely off, but I know equalizing cylinder/banks intake pressure can have a positive effect.

Twice the V-Stacks for twice the power, baby!

looks like we had it right
The intake manifold features straight inlet tracts to the two central plenums that, in turn, have trumpets individually cast at the top of the tracts for each cylinder, to ensure optimum air flow to the cylinder heads. A rotating drum - actuated pneumatically by the engine control unit - compensates for variations in the effective volume inside the two plenums to optimise the intake resonance characteristics and therefore maximise the torque curve throughout the rev range.
