Fuel Injector Problem

So I was reassembling my intake this afternoon, when I heard a bad noise while tightening the last bolt. One of the injectors was slightly misaligned and busted, causing the noise. Unfortunately, it also dented the cylinder head right on the edge of where the injector SHOULD have gone.
I'm looking for new injectors now, I figure I may as well replace all 4, but I wonder whether I need to worry about the dent on the head. Thoughts?

(I would post a photo of the head, but I'm forum retarded and don't know how...)

A picture would help. But just taking a wild guess I'm going to say no the dent shouldn't be a problem. ;)

Not sure what year your miata is but I've got a set out of a 2001 that has 36k miles on them taking up space in my garage. If they'll work I'm sure we can figure out a good deal.
