350x motor mount bolts (STUCK)

[johnny's X]

Does anyone know a trick to get motor mount bolts out of a x motor when they are really stuck. I had to cut the mounts on the frame to get the motor out and now i still cant get the bolts out

heat the nuts with a torch and twist off. Will have to repaint though. Or spray with Let Go, or comparable penetrating oil, and let sit for a while and see if that get it

Tried the heat with air chisel and it did more damage than good. I might have to take it to machine shop and have them drill it out
