TB42 head bolt torque settings

1st stage = 29Nm
2nd stage = 57-67Nm
3rd stage = loosen bolts completely
4th stage 29Nm
5th stage 69-74 degrees using an angle gauge or 64-74Nm

Are the settings the same for a 4.2 diesel with a turbo??

[YNOT]

I can't find the settings for TD42 turbo but they are most likely the same as the naturally aspirated TD42.

TD42 head bolt torque settings

1st step 49 to 59Nm
2nd step 96 to 108Nm
