Following is elaborate bolt tightening sequence for Forester 2.5L SOHC cylinder head. Is this what all DIY'rs are using?

2) Tighten cylinder head bolts.
(1) Apply a coat of engine oil to washers and bolt threads.
NOTE:
Bolts with pink marks on their bolts heads must be
used for (c) through (f).
(2) Tighten all bolts to 29 N·m (3.0 kg-m, 22
ft-lb) in alphabetical sequence.
Then tighten all bolts to 69 N·m (7.0 kg-m, 51
ft-lb) in alphabetical sequence.
(3) Back off all bolts by 180° first; back them off
by 180° again.
(4) Tighten bolts (a) and (b) to 34 N·m (3.5
kg-m, 25 ft-lb).
(5) Tighten bolts (c), (d), (e) and (f) to 15 N·m
(1.5 kg-m, 11 ft-lb).
(6) Tighten all bolts by 80 to 90° in alphabetical
(7) Further tighten all bolts by 80 to 90° in
alphabetical sequence shown in figure below.
CAUTION:
Ensure that the total “re-tightening angle” [in
the former two steps], do not exceed 180°.

Thanks

That's what I just used on MY04. Granted, the 03/04 manual WAS different, but I have always used what the RS, Legacy, Outback and 99-02 SOHC's called for, which is exactly what you stated.

Step 3, back off 180 in BACKWARD sequence .... ie f back to a. Then 180 again.

The 2 ODD colored bolts are in the center. I have seen some pink, red, black and green to date. Sometimes the 4 corners are colored, others only the center bolts are.

Thanks, I'll post my experience after doing the head gaskets early next year.
