We don't know without testing, and unfortunately the difference between the two will likely be much smaller than what I can measure on the road.
I did, however, redo the grill blocks--but not because of that; purely for aesthetics. I used the same heavy plastic I made the mirror blanking plates out of and was able to cover part of the center section of the upper grill in addition to what I had before:

We can't know where the stagnation point is without measuring, or how large an area is stagnant. I don't even know where it is/how big it is yet, since I haven't tufted the front of the truck or measured pressures. Plus, if this truck behaves like the 1988 Chevrolet C/K and 2015 Ford F-150 (two of the papers I mentioned above), the stagnation point will change with other modifications such as an air dam (I'll be testing various air dam configurations in the coming weeks).
