Engine studs

[scfire]

I removed the head on my 350f to fix the leak with new gaskets and found that two of the studs have worked their way loose. Is it advisable to pull these and add some thread lock or just tighten them back up without it.

no harm in thread locker and that's the way i would do it
the threads aren't wallerd out are they ?
