Everything about the truck is brand new, and has never been in motion. The laws of physics will bring the engine together because each piece is its own separate part, and the motion of turning over and firing will seat these pieces together making it one gigantic part. The headgaskets will completely seal, and so will all other gaskets once everything has expanded and seated itself properly. However the main focus are the piston rings and cylinders, but I provided a link down below. Also when you buy a brand new item like a new audio system or computer do you sit there and hammer the thing until it breaks? No you baby it in and use it like you normally would because everything is still loose and needs tightening up. However I completely agree with whoever said drive it just like you would a year from now. That will make your truck cater to that exact style of driving, and you won't have any problems. Of course hitting the interstate a couple of times and giving it a little gas would also be helpful because the last thing you want is a babied truck. Everyone is basically right, but all of what they are saying is just one part of what you should do. Also Ford is just trying to cover their own *** so if any hot rodders get ahold of a new truck they won't be so tempted to thromp on it as much if they see something like that in the manual. It also acts as somewhat of a guideline for those who are wondering what a break in period is and how long you gotta do it.
P.S. Oh and Bucko doesn't parade this sub-category of the forums so you may wanna do a search next time if you're curious because I've already seen a few of these threads before.
