sratched a head's flange: how serious is it?

[Konstantine Bogach]

Hi.

When taking off a head on a junk yard I droped it on a block and
scratched flange surface. I did not take the head from a yard because I
am not sure about consequences and cost of machining. Scratch is not
very deep and is not going all the way through  from inside to outside.
Is it still worthy to take it?

I have never rebuilt head by myself and I wanted the head just to play
with and learn its internals and how to rebuild it.  What can I do to a
head besides to make another rebuilt stock one?  I mean what kind of
mods is worthy to do ( besides modified camshaft) ?  I would appreciate
if someone point me to an  information source for additional injectors
as well (are they installed in intake manifold?).

Thank you.
Konstantin Bogach.
