Per, I'm not sure I'd want to re-use those.  That dent
looks pretty bad, plus if you look around the top ring
you can see some pits from detonation.  My MC pistons
have a real small 515 0487 part # on top.  Right about
where your dent is.  I'd sell them to you, but they
are in far worse shape, plus it's my
paperwieght/reminder not to run my car lean.  I bet
you can find a used set pretty easy, most are usually
in perfect shape.
