Just replacing head gasket

Same as a 16v head: 29Nm, turn 90 degrees, turn 90 degrees.
Tighten every bolt in each stage before moving to the next stage, starting in the middle of the head and working out in an X pattern.

It should be noted that method only applies to a setup with stock headgasket and stock head bolts. If either of those change so must the tightening method.
