Gentlemen,
Any suggestions as to how to get the glowplugs out of an alloy head
without stripping the treads? I gather they can be problematical.
I was thinking about putting several hundred amps through them between
the outer threaded part and the surrounding alloy as an alternative to
using an induction heater to break the bond, since an IH is useless in
this situation. But I'm not sure if that's a good idea or not. Anyway,
your tips welcomed.

I've always been successful in removing glowplugs
Some advocate spraying WD40 and leaving for a couple of days to soak.
Some advocate going backwards and forwards at the start and when/if it
gets tight unscrewing.
Have you got any out? What's the vehicle?

I don't have much faith in WD40 as a releasing agent. In fairness to
the brand, that was never what it was intended for originally. In fact
I have very little faith in releasing agents in general. One can
probably do a better job for oneself by mixing IPA with ATF and
letting that soak in for several days with repeated re-applications.

It's a 6 pot Beeme circa 2006, dunno the exact model off hand. M57
engined, though - that much I do know.
