Does anyone have the specs for the head bolts. Thread pitch,length, grade.....?

Thanks

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.

Jim at EuroTech Services International has them in stock ( or had them ), I just bought a set.

I have some spare used ones if you need just a few.
