If you aren't prepared to go all the way to "can't be tight if it's a liquid", leaving it as it is and taking it to a shop is the right call. It's possible, but unlikely, that you could get those stubs to unthread with any sort of mechanical-only solution like vise grips or a stud removal tool. It's more likely that either of those options just break off what's left above the gasket surface. Easy outs or improperly attempted drill+tap jobs can leave you with broken off tool steel in the middle of the hole, making everything much more difficult. The route I would go if trying to fix that would be to take a larger nut that fits on/around the threads and weld it onto the stub, giving you both somewhere to pry from and also shocking the whole thing with heat that might break up the corrosion. If that fails or the threads are absolutely demolished (say, whoever was in there last cross-threaded both upper bolts) then you're looking at drilling it out and some form of thread repair (helicoil, timesert, etc).
