get a 3/8 impact on them... something to jar them around but not enough umph to straight up snap them off... the impact tends to free rusted and galded things up... used to work at an exhaust shop and manifold studs would usually come out with the impact or some heat...if the engine wasnt alreay out i'd actually tell you to run the truck up to operating temp and take everything loose. if all else fails put a little heat to them i dont recommend heating the head extensively (un even heating causes warping) and sometimes they have to break... as long as they dont break off flush with the head and leave about 1/2 inch shank a stud extractor will usually do the trick.

one problem with the nut idea... usually penetration only makes it to the tip of the bolt and side of the nuts... it doesnt usually yeild too much strength for torsional movement unless you can get to the backside of the nut and put a tack or two there too... welding a nut is a perfectly fine solution; if you have a stud extractor i'd try that first
