When I hit similar on my Ruby with head studs I found that plumbers freeze spray in conjunction with a judicious application of heat prior to spraying the stud worked a treat.
I heated the stud and surround area then using a short piece of metal tubing over the stud spraying into the tube to cool the stud rather than what it was stuck into then went back to the double nut way of providing leverage. The extreme cooling allowed the stud to break free of the corrosion holding it. Some took two or three attempts but I removed all but one this way.
Worth a try.
