Default Head exhaust stud

Does anyone know how long the stud portion is that threads into the head? I'm wondering how deep I need to drill to get the old stud out.

I ve used RTV high temp silicone on shovelhead exhaust studs with good results. It seems to mitigate vibration and fusion issues. Easy removal also.
