In my MB tech book all 602 engines have the same torque settings for the cylinder head.
you torque the head in 5 stages!
1) 15nm
2) 35nm
3) 90deg rotation of the bolt
4) wait 10 minutes
5) 90deg angle of rotation
Usa a solid breaker bar to do the angle of rotation stages
Start in the middle & work back & forth across the head working to the outside.
A little secret, after the first two stages put a paint dot on each bolt facing the intake. after the first angle(stage 3) the paint dots will be pointing forward & after stage 5 they will be towards the exhaust! That way you will be assured that they all got the same torque!
