I would have to say that you should reglue these with new glue.    grin.

No.. seriously... take the action and put it on the bench. Remove every
loose head and carefully reglue them after removing old glue from the
shanks holding to the strike line. Mark them with chalk as you go and when
done and glue set, do the rest just to make sure the problem is solved once
and for all.

I do not recommend any quick fix or halfway measure when glue failure
manifests itself to the degree I am reading in your comments. It really
doesnt take so much time to reglue them all on the bench, and you can give
the action a good look over at the same time.
