How to remove stuck bolts in motorcycle head(Suzuki GS 700, 1985)?

All right, ALL of the bolts below the head cover are stuck. The camshaft bolts will break or destroy my wrench before I can remove them. The biggest worry I have is some 5 millimeter Allen bolts that attach my oil pipes to my engine that I am rounding out just trying to unscrew. I CANNOT afford to break these, for these are unique bolts. So no breaking or drilling is possible. These can withstand me leaning on my L-wrench with all my weight, and the metal will give first. I have tried Liquid Wrench, WD-40, pounding on it with a hammer, it is not reverse-threaded, butane torch, and trying to tighten it. Any good ideas here?
