Here's how I'd straighten it.
I'd fixture the head in a vise or tight fitting tube. Slip an axle up the shank ending right where I want to bend, and gently lever it home. You can control exactly where it bends by the position of the axle, so observe what's happening as you straighten it and adjust if necessary.
One thing you don't want to do is overwork the dough. So get it close in a single pass or two, but no back and forth trying to get it perfect.
