Ronnie, at the assembly point you're at, compare your upper gap to the side gap. If your side gap is less than your top gap, step back from the side of your truck by 20' or more and have a look at it. If it looks like the nose is down, then you'll need more spacers under the radiator support. If the gap is even, loosen the hinges at the cowl on both sides and push your hood back towards the cowl. If it won't go back any further, you might need to adjust your hinge holes (file) on the cowl to allow the hood to move back further. Keep in mind, you might need to do this dance a few more times as you get all your parts bolted up.
That's usually the first thing I do is square up the hood, get the fenders and everything else close, then go through the hood adjustment procedure, make sure I love my hood vertical to cowl look, then bring the fenders up to the hood and close those gaps. It is important to have all the proper weatherstrip in place so the hood sits flat at the cowl like it should.
