Stud kit Head ARP 9 Stud With Rocker Studs and 12 Point Nuts
$159.95
Austin Mini Competition Head Stud & Nut Kit
Competition head stud kit (11 studs, nuts & washers). Also includes rocker studs nuts and washers.
This special kit was developed to replace the increasingly inconsistent standard items. The studs are manufactured in selected hi-grade steel and produced to exacting specifications. These studs do not stretch, so they pull the head down, not the thread up; this vastly increases head gasket life, even on high compression engines. Special thick washers, countersunk on one side, help clamping capability and reduce thread bottoming of the nuts. The 12 point skirted nuts help to increase torque accuracy through better engagement. Note that even replacing the head bolt with a stud, only torque that stud to the factory recommended spec(25 ft/lbs), the other studs can be torqued to 65ft/lbs with oil, 55ft/lbs with ARP lube. (Rocker studs 25/20)
