The hood hinges on the inner fenders and the hood hinges where it joins up with the hood will need to be adjusted. The hoods I have adjusted were thru trail and error when adjusting the hood hinge/hood. Remove the hood latch mounted on the radiator support. this will allow a pre check as to how the hood is closing. Use a painter tape (color blue) as Pre'80 mentioned will help existing paint job from getting chipped and scrapped. Use the tape where you feel necessary. Once you have the hood closing as it should, re-install the hood latch loosely, then close hood and eyeing where the hood latch should be mounted and bolted. The hood latch will need to be adjusted using trail and error process as mentioned.
The hood / hinge adjustment does take time and patience. Usually after a few adjustments, you'll be able to determine what adjustment will be needed.

This hood adjustment and latch adjustment are best done with minimal distractions and having lots of free time. Rushing this job will be notice for a long time.

Inspect fenders, hood, grille, inner fender, doors for adjustment, and worn parts or bent parts .

FYI, Worn out hood hinges, or bent hood hinge, or worn out hood springs will cuase major hood alignment issues with the cowl. Inspect those hood hinges and hood springs. Check the hood for the rubber bushing, those rubber hood bushing will hit the out fender when the hood is closed. These bushing kind of help to line up the hood when the hood is closed.

Oh-ya, I saw your truck gallery and your hood needs the hood/hinge/latch adjustment.

Use some marvel mystery oil to lube hinge, latch, and moving parts prior to any adjustments. It will help with all the hood opening and hood closing that will be going on.

Best of Luck,
