Can I remove 40 year old seized bolts using an induction heater?

Using a Solary Magnetic Induction Heater, I successfully removed all 12 of the 40 year old exhaust manifold bolts on this PRV V6 motor.
The induction heater I used was bought on Amazon and is simply amazing. It prevented me from snapping any of the bolts off and having to drill and tap new threads:
