NO thread lock on head bolts.

2) Tighten cylinder head bolts.

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

threads.

(2) Tighten all bolts to 29 N⋅m (3.0 kg-m, 22 ft-lb) in

numerical sequence.

Then tighten all bolts to 69 N⋅m (7.0 kg-m, 51 ft-lb) in

numerical sequence.

(3) Back off all bolts by 180° first; back them off by 180°

again.

(4) Tighten bolts 1 and 2 to 34 N⋅m (3.5 kg-m, 25 ftlb).

(5) Tighten bolts 3 , 4 , 5 and 6 to 15 N⋅m (1.5 kg-m,

11 ft-lb).

(6) Tighten all bolts by 80 to 90° in numerical

what i would say is "haynes is an introduction to automotive repair"

 

not the 'how to' manual for subarus.

 

it is an introduction to auto repairs for which ever vehicle you own, not the ultimate solution on how to.

 

way better than no manual at all , but no where near the info you really need.

For Correct information for your specific application, post the year and model of the car, and what engine you're working on (Year of the engine too if it isn't the original engine), and someone here can post the correct torque specs and tightening sequence for that particular engine. That way you get it right and don't have to do it all over again in a month. :eek:
