Dent in Header Panel

Hey guys,

Here is the original header panel that was on the car when I bought it. As you can see, it has a huge dent! Question is can this be fixed? As in fixed like you would know it ever had a dent. if so any idea what something like that would cost to fix if I took it to a body shop? I purchased a replacement header panel already but I am curious So I can figure out what to do with it.
