Torque value for 2013 cylinder head

[Spud Perona]

Torque specs for 2013 denali hybird, had changed bad lifter. Now i can't find how much to torque down head

[davester]

It might also have a pattern to torque the head down as well...  And might have torque-to-yield bolts (as in, single-use bolts) [I don't know one way or the other, but you want to find out before doing it].
