I personally have no idea how to upsize images keeping detail easily.
Easiest i could do is upsize it then go over and re make the whole entire head perfectly to the old image.
Not a simple task to say the least
Edit: Who made the head again? If the maker has the original file still and they did it in a size larger then 512x then maybe they'll give it to you.
I do all my images in 800x and downsize to fit what i want
