I just found out that the previous owner had heli coiled one or more of the exhaust studs. Will I need a new head? If so what's the best?

Here's what I suggest. Get some high temp RTV from your local economy auto parts store. It usually red stuff that stays soft after it is cured. Remove the studs and clean the threads both on the studs and in the head. You might want to use compressed air and blow the air through the taped hole in the head from the inside, when you have the valve cover off. Make sure you don't get a bunch of dirt and crude into your oil, though. Next coat the stud liberally with the red RTV and screw it into the head to the right depth. Clean the excess RTV off the outside of the head where the manifold gasket will sit. Let the RTV sure for the prescibed time. Then put some of the RTV on both sides the manifold gasket and put the header on. Tighten the nuts to the prescibed torque (tight) and let sit until the RTV is cured. Hook the rest of the exhaust up and try it out. If it doesn't leak anymore you've won. If it does then think about getting a new head.
