Torx Racing Spec head studs let you run more boost and compression without worrying about head lift. ARP makes them from 8740 chrome moly, heat treats them to 190,000 psi and rolls the threads afterward for better fatigue tolerance.
Ground washers and nuts come with the set, and the studs have been tested at 600 hp and 10,000 RPM.
