what do you mean "badly corroded"? I'd start by cleaning it off - if the
corrosion only penetrates a little (.010 or so), then I'd ignore it - if
it
goes 1/2 way through, I'd replace it - I don't believe it is reverse
threads, but I haven't personally removed one - and I've only pulled about
6
heads, never seen a corrosion issue -
If you really need to change it, first, get a replacement - it would be
even
worse to get it out and discover you can't get a replacement. there is a
special tool called a "stud remover" that you can put on a 1/2 inch
breaker
bar to remove studs - but it will chew up the stud and you won't be able
to
reuse it.
I wouldn't sand it down, I would use a scotch brite pad and get the
corrosion off, and then look at it and see what is really going on - and
try
and figure out why it happened.
