Default Cross Threaded Heads! UH OH

I bought a car with AFR 185 heads. It had shorties on it and I just recently (tonight) put on a brand new set of Hooker Headers L/T's. The bolts were a pain to install because whoever installed the shorties on the AFR's was cross threaded the heads. How do I fix them as these are $1200 heads!!!!! Any help with this would be GREATLY appreciated.

How many holes and where in the heads? They will most likely have to be pulled and helicoiled. That sucks dude!!!

I think it was like 3-4 holes. Two on each side! Yeah it sucks. Headers are a bitch. Those hookers werent fun at all. Never seen nothing like them. What is a heli-coil? Im not a mechanic and this is my first real project car. I just hope I dont have to buy new heads!!!

Thanks guys. I feel Much Better now. I knew when I bought that car that cheap with those heads on it, something has always got to go wrong! Alright, now those hours spend putting headers on, now Ive got to take the heads off. I guess while im at it i can have them P/P'd and take that ugly black paint off of them.
