Yes, the body was assembled around the headlight bar and there is zero manner to remove it in one piece unless you want to take a chopsaw to both of your front fenders
before removing the hood, you should consider this trick that I was taught many years ago by an old timer.
drill two small holes through each body hinge into the body steel. I drill 1/8 inch holes, which are a perfect fit for 1/8 inch aluminum shank rivets
when you go to replace the hood, have two helpers position the hood and hinges, then install four rivets in your four holes, tighten things up and you will return to your original alignment
Honestly, Simon’s advice to remove the deflector, and if necessary the hood, will provide more than enough access to that radiator and fan assembly
