It isn't published to my knowledge. I just use a cross pattern. It isn't a long head like on a straight 4 or 6 cylinder engine. If head gasket replacement torque in stages, I start at about 1/3 of the final, then 2/3 then final. If a re-torque, back off about 1/8 turn then go to torque value. You can be under torqued if you don't as you have to overcome initial resistance to movement.I know this an old thread but where can I find the proper bolt torqueing sequence for the head bolts? Cant find it. Thanks in advance
