I would start by using multiple applications of a good penetrating oil like PB Blaster over a period of days. Then apply heat from at least a MAP gas torch or small tip acetylene torch around the area of the head where the stud is screwed in and gently try to unscrew the stud. It should go OK but remember - heat is the real trick. Good luck and if they don't come out easily - more heat and patience.

Sorry if that was too harsh.
Welding nuts to the studs wont hurt the heads, I've had good results with that method countless times.
