I'm far from office now, when I'll be at work, in Monday I will post you document from WIS with torq. table and bolt tighteniung order.

I remember valve lashes values only... 0.4 mm in., 0.6mm exaust.....

Do you have leaking gaskets? if yes, check head surface in exaust passage area around water passage, and resurface in any machine shop.

stage 2 37lb-ft
stage 3 74lb-ft
stage 4 148lb-ft
stage 5 90deg or more
stage 6 90deg or more
from the mbe 4000 service manual
in a cross pattern
they look like torque to yield bolts
are you just re-torquing the head or has it been off the block?

if gasket leaks, no reason to retorque. Threads in engine block may be damaged.

usually head gasket leaks becouse of bad surface in exaust passage area.
