What's the Volumetric Efficiency (and airflow) of a 32 valve ABZ engine?

The model predicted only 3 hp less, 308 hp @ 6000 rpm versus 311 hp @ 6200 with the AKB model.
The valve timing events per the Bentley were the only change I made in the model. There could be other differences between the motors, not the least of which could be the cam profile, even if opening and closing events remain unchanged.
For the ABZ motor, volumetric efficiency was also almost unchanged,
... 90% @ 4000 rpm
... 97% @ 5200 rpm
... 94% @ 6000 rpm
