Cylinder head studs are about creating the most consistent cylinder/head platform [stability] no matter what the intended use.
Supertec is a good choice for those interested in improved design features.
Precision ground, heat treated, rolled threads
Quality corrosion resistant aged 17-4PH steel

Additional threads at case end for more engagement [important for non-inserted mag cases]
