MG Car Repair/Cooper S head studs


I know my query is not related to MG, but Classic Cooper S is very much related to it and I cannot really find anyone else to help me.

The Cooper S cylinder head is secured to the block by 9 standard studs and 1 additional special stud and 1 special bolt located at the front and rear end of the head.

Can you confirm at which end is the stud and which is the bolt. Incidentally, the front is the one closest to the 6nu6water pump.

Many thanks.

Hello Yahaha

On a Mini Cooper 'S' the special bolt was fitted at the front (water pump end) of the engine and an extra stud was fitted at the rear (flywheel end).

Do not over tighten them.  They only need a torque of 25 ft lb.
