Competition head stud kit (11 studs, nuts, and washers, with EN24 nickel-chrome moly steel studs, four (4) long and seven (7) short.

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.

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.

Question:
Will this kit fit a 948 MG engine?
Answer:
Yes it will. However, you don't need an 11-stud kit but a 9-stud kit since the 11 stud kit is for Cooper S engines and other high performance 1275's:

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.
