If your high-compression or high-RPM motor blows head gaskets or blows coolant, it is likely that the head studs are not keeping enough torque pressure on the cylinder head. You can only re-torque a stud so often before they stretch and lose strength! These ARP studs are manufactured of high grade steel: they don't stretch so you pull the head down not the stud up. 9-stud kit with special machined washers and 12-point nuts are included to increase torque accuracy through better engagement; watch out for ARP kits sold under this part number, but equipped instead with cheaper 6 point nuts! Rocker studs and nuts are also included. (As a point of reference, the cost of this kit is less than stock studs alone!). Fits Classic Mini, Sprite and Morris Minor. Studs can be torqued to 65ft/lbs with oil, 55ft/lbs with the included ARP assembly lube.

ARP Bolts & Fasteners

Fastener Retention Overview There are three methods that can be employed to determine how much tension is exerted on a fastener; using a torque wrench, measuring the amount of stretch, and turning the fastener a pre-determined amount (torque angle). Of these methods, use of a stretch gauge is the most accurate.
Competition head stud and nut kit
Created: January 30, 2000
This kit has been produced by Mini Spares to reduce head gasket problems on performance orientated engines, especially those utilising large over bore sizes. Standard type head studs and nuts are mass produced which unfortunately compromises the specification of the end product. Worst affected are the threaded portions which create problems during torque-down; thread deformation, stud distortion and possible stretch, off-square seating of the nut to head and so on.
