I hate to say this... but my experience with body adjustments is extremely limited. I have the luxury of having an in-house body shop where I work. The following are body gap specs:
14 HOOD TO FRONT FASCIA 4 +/- 1.5
15 HOOD TO GRILLE 6 +/- 1.5

The following is hood install procedure:

With the aid of an assistant, position the hood on the safety hooks on the hood hinges.
Loosely install the lower bolts (2) on the hood.
Loosely install the upper bolts (1) on the hood.
Align the hood with the bolts (1,2) to coincide with the witness marks.
With the aid of an assistant tighten the hood hinge bolts (1,2) to the hood. Tighten to 10 N¥m (88 in. lbs.).




Install the gas prop rod (2) to the hood at the top then install the gas prop rod retainer (1).
Shut the hood and insure that the hood shuts properly and securely and that there is a uniform gap around the hood to the front fenders and grille.
Verify fit of hood to vehicle body. Adjust as necessary
