Not difficult, just have to be patient and careful.Super easy, I straighened my by placing it in the chuck of a drill, slowley rotated it to see which way it was bent and hit it carefully with a rubber mallet, did this untill as far as I could tell the valve was straight. Then flipped it around and put the other end in the drill and did the same again. End result, pretty straight exup valve.
Much better to have a working EXUP than an empty one.
Or just take it to a machine shop, it will take them a few minutes and they will be able to get it dead straight with within a few fractions of a milimeter.
