Will this hammer/frogspawn grow back?

Died due to 92* temp last week. Glad the bigger colony survived but only 3 heads of the smaller one did.
Will the other heads grow tissue again? Or that’s it and I should cut them off?

I doubt the old heads will grow again but it is possible. It will put on new heads

White heads gone.
Do you have a plan for when it gets hot again?

White heads are goners and won’t grow back. I’d frag them off as all they’ll do is grow algae.
