When boosting or increasing boost on an engine, an ARP head stud conversion is a no-brainer. Not only do ARP studs offer a much greater yield strength (force required for bolts to stretch under tension), converting to studs from bolts offers much more accurate and repeatable head torque-ing. As a consequence, you can achieve more even clamping of the head, reducing the chance of warpage or blown headgaskets when pushing your engine that very last bit. High compression normally aspirated builds will also benefit from these features as well.
Finally, studs allow for easier and faster head removal and replacement as they help to guide the head into place. We use ARP whenever we have a head off an engine we are working on. After all of these reasons, need we say more?
