Auto Parts: broke pontiac sunfire please help, pontiac sunfire, ohv engines

Question
I have a 96 pontiac sunfire and i need to replace the cylinder heads on it and cant seem to find a used one. I was sold one from a 99 cavalier and it did not fit now I am out the cash i so
spent can u please tell me what cars are compatiable with my car so i dont get burned again. i need to replace the whole thing. I had my spark plugs changed and the person striped the cylinder for plug. He put a insert in to fix the problem but then the insert ended up down in the cylinder head. Please help. thank you  

Answer
    Well, my first suggestion would be to take the original cylinder head to a machine shop to have the threads repaired (easy to do off the car and really difficult to do properly on the car).  Otherwise, 95-97 Cavalier and Corsica with OHV engines.  I'd also recommend buying a rebuilt head, as you never know what is wrong with a used head (like, why did they take it off of a perfectly good engine?(which they obviously did not)).
