ok here is the sequence

step 1- 22 ft lbs
step 2-55 ft lbs
step 3- loosen all bolts 180 degrees
step 4- loosen all bolts an additional 180 degrees
step 5- center two bolts only 27 ft lbs
step 6- all others to 132 ft lbs
step 7- tighten all olts to an aditional 90 degrees
step 8- tighten all bolts an additional 90 degrees.

It is very im;portan that you follow these steps very very closely. If you don't serious head warpage or gasket damage WILL occur

no mention of oiling the threads on the bolts? Pretty sure you need to.

Oh LORD YES!!!! Do not use the LOOSENING sequence to TIGHTEN the headbolts. You'll scratch your head wondering why on earth Subaru wants opposite corners of the head torqued tighter than the rest. It all makes sense when the center bolts are torqued correctly.......

We'll see if Cometic's "reusable gaskets" really are. Since the motor hadn't run with the wrong torque values.....I'm keeping my fingers crossed!

Your right, I should have added useful info instead of acting like an armchair mechanic. I will do that asap.

Default Cylinder Head Torque

I've never had a head off, but here's some info on installing a DOHC head. However, I think this came from the 2002 Impreza?? It doesn't give you a specific torque spec, but just the 80 degree angle B.S.
