There are 32 studs holding each head; pictured on the right are 62 of them. There are 3 different stud lengths used:- a)=4.375", b)=5.5" and c)=6.0". Shown in the table below is the position of each type; the numbering is taken from the front. Cylinder heads are identical, so can be fitted to either side of the block. Studs on the inlet sides run in reverse sequence from 'A' bank compared with 'B'. Problems encountered with extraction are noted below:-
Final resolution to the stud problem has been put on the back-burner until the state of the rest of the engine has been ascertained. |
