Fitting heads on my 02 sti I used the workshop manual which gives the below head bolt torque sequence..

1) Install the cylinder head and gaskets on cylinder
block.

NOTE:
• Use new cylinder head gaskets.
• Be careful not to scratch the mating surface of
cylinder head and cylinder block.

2) Tighten the cylinder head bolts.

(1) Apply a coat of engine oil to the washers and
bolt threads.

(2) Tighten all bolts to 29 N·m (3.0 kgf-m, 22 ftlb)
in alphabetical sequence.

(3) Tighten all bolts to 69 N·m (7.0 kgf-m, 51 ftlb)
in alphabetical sequence again.

(4) Back off all bolts by 180° first; back them off
by 180° again in reverse order of installation.

(5) Tighten all bolts to 49 N·m (5.0 kgf-m, 36 ftlb)
in alphabetical sequence.

(6) Tighten all bolts 80 to 90° in alphabetical sequence.

(7) Tighten all bolts by 40 to 45° in alphabetical
sequence again.

NOTE:
Do not tighten the bolts by more than 45°.

(8) Further tighten all bolts (A) and (B) by 40 to
45°.

NOTE:
Ensure that the total “re-tightening angle” in the
previous two steps do not exceed 90°.


As you can see the final stage is just tightening the middle two bolts 'A' and 'B'

I was just double checking online and i found the exact info on nasioc but Everywhere else I find info has the final two steps as 90deg all, 90deg all. There is no tightening of just A and B on the other guides I've seen.


I did find an old post about classics where a guy (I think it might be Phil of Barratts?) mentions the same as I used

So, have I got the right info? I think it's right but I have seen people quoting the classic settings for newage when advice is given.
