Removing a loctite bedded barrel

[Klem]

I wonder whether an induction coil heater would work in getting off that block.

It was mentioned here recently in a thread on brass annealing and I have bit the bullet and bought one - it hasn't arrived yet.

You could adjust the coils to go around the gas block and heat the whole block evenly and at the same time. With a torch you'd have to go around it by bit and I wonder if parts of the block would cool as you were heating other parts. I know it is a lot of money but if you already had the device surely it would work. I also see cheaper induction coils which are just exposed circuit boards on Youtube.
