Shank length of cylinder head bolts are 112max according to WSM.
Size is M12. Grade not provided - I would suggest they are proprietary (MB spec) bolts.
I know some models actually used studs with nuts on the top instead of bolts - early models perhaps ?
OK, just found it - before engine number 678 155. They can be replaced by bolts.
