That's exactly what I suggested in another thread when someone pointed out that it would be very hard to measure total head. The only problem is that most of the pumps commonly used in watercooling systems (Eheim, etc.) do not publish good performance curves that I know of. However, the manufacturer of my pump does publish such a curve, and I was thinking about doing some quick tests to determine the resistance through my new rad and block when I get them.

And I agree with you that it's nice to see the theory behind pumps and head loss in Laguna's manual (I actually looked at one of their pumps for my current system... the 3000 I think). Now all we have to do is get Dangerden or DTEK to publish flow-resistance curves for their blocks
