Was any thread locking compound added to the screws when they were installed? If there was, you may need to apply some heat to the screws to melt the thread locker. Small propane torch would work. Once the thread locker starts smoking around the threads, you should be able to back the screws out.

Tried using heat and got one out but could not get the other unstuck and ended up with some nasty gashes near the screw from the drill I was using slipping out.

Heat should work. I use a plumbers torch and don't blast it with the heat all at once. I like to use propane, not mapp, and apply the heat for a few seconds wait a second apply more, etc... I found it you use too much heat all at once strange things might happen to the finish etc... Better to be gentle. And might want to wear leather gloves.
