Want a broken 1500 head

[Nolan Penney <npenney@erols.com>]

I'd like to try my hand at some head work on my 1500 Spitfire.  But 
first I'd like to practice a bit on a 1500 head that's no good.  That 
way when I go to deep and hit water jackets and such, it will be no 
loss.  So, if any of you have a broken or otherwise non-repairable 
non-usable head that you'd like to get rid of, I'd be most appreciative.
