Scott,
Is the problem that the studs are rusted away or is it just the nuts? If it's just the nuts, try using PB Blaster, Kroil or another good penetrating oil on the nuts while they are hot. Don't bother with Liquid Wrench or WD-40, they won't even begin to help. Take your time and work the nuts off without twisting off the stud. Then apply new brass nuts. They won't rust to the stud.
If the problem is the studs themselves, you'll have to try removing them any way you can. If they twist off, you can drill and retap, but you'll have to center everything VERY CAREFULLY to avoid damaging the head. If you don't feel up to this task, you can remove the head and take it to a machine shop and have them remove and replace the studs.
Threaded inserts or helcoils should work fine in this application.
Removing the studs yourself might be easy and it might be one of the most difficult things you ever attempt. One thing for sure, if they don't come out easily, you will probably need to buy or borrow an oxy-acetelyene torch to use to heat things. A propane torch just won't cut it. Been there, done that. There are several tools that will help remove the studs, but easy outs aren't one of them. Don't waste your time with them, they just end up broken off in the hole and are extremely hard and nearly impossible to drill out. One tool that a lot of folks swear by for this is a left hand twist drill bit. It is the reverse of normal drill bits, so as it drills into the stud, it twists the stud out. If I was doing this, I would use a drill press with the head held in a vise so the head would have less likelyhood of being damaged.
If the stud has enough sticking out of the head, you might try welding a nut to the end of it. This works well also. The welding heat loosens the stud and it will come out easily (sometimes).
Unfortunately, a lot of times nothing will work and the head will either have to be repaired in a machine shop or replaced.
Try to get it out yourself. You've got nothing to lose and a lot to gain.

Good luck,
Phil
