It is a good idea to do this as old stud threads may not give you the correct torque reading. Buy your studs from Third Gen Parts, as they will have the correct type of threads. https://thirdgenauto.com/ Tom

I recently knew a guy who rebuilt an 85 HP V-8 for a 1937 Ford. When he replaced the head studs, he "tapped" the threads in the block before threading in the new studs. When the time to start the rebuilt engine came, several of the head studs were leaking coolant from the water jacket. Upon further review, we found out that the threads should have only been "chased" and not tapped. Eventually he added enough stop-leak products to stop the leaking head studs. Still, we are considering NOT replacing the head studs on the next V-8 rebuild project to avoid this risk of leaking head studs upon completion.

One thing that works to stop head studs from leaking after they have been replaced, is to coat the threads on them before installation with Permatex #2 non-hardening sealer.
