Rudy, on that '67 diagram of the pump assy, the flat surface of the internal housing shoould be adjusted towards the surface of the pump vanes.
There certainly will be more power used by an optimized pump. However, I believe the goal here is to get the assembly back to the OEM design specs; as such there obviously is a limit as to how "good" or lossy the pump will be.
I guess for race purposes, the pump clearance can be relaxed, (less power wasting) at the expense of heating. An interesting trick...
One way to estimate how much power is used by the pump is to check the specs of an electric pump and get the HP figures from that. They should be fairly close.
