Hi Closed,

Humble recommendation for your one (1) stud, & good practice suggestion I heard years ago from a highly intelligent professional vintage mechanic:

1. Remove head, remove all studs, replace all studs with new studs -- do it right ........... do it once.

2. Reason:

Whether a material mystery or not, a changed molecular arrangement, an altered steel tempering, a stretched & stressed cross sectional bolt area, so "few" studs spaced far apart on a Model A head, or many others reasons one may have heard, a very wise move recommended by Ford Technicians in the 1930's was to remove all old studs & provide all new studs every time a Model A head is removed.

3. For me, simple analogy:

In my humble opinion, at under $15.00 for a set of regular, new studs, & realizing the trouble to extract just one (1) broken stud, if someone decides to try using old, even just "once-used" stretched studs, he probably will also try to take a chance on changing his underwear once a year, & still sit in a chair all night and all year, & wonder why young pretty women are refusing to dance with him on a Hot Summer Saturday night.

Hope this helps.
