I can help you with this but I have to ask one question. Have you already taken this apart and putting it back together? Did you rethread all the head bolt holes because they strip out when you tighten them and you will ruin the head gaskets. Let me know, I have don't this job quite a few times. I'll have to look up the actual torque specs. Also you are wanting the spec for the cylinder head bolts and not the cylinder head cover bolts right?

looks like there is special sequence to reassemble and tightening, a quick note replace any bolts that have two punch marks.tighten as follows: x x x x x 10 4 2 6 8 x x x x x 7 5 1 3 9 torque all down to 15 ft lbs torque to 30 ft lbs plus 90 degrees. Good luck!
