I have attempted the impossible (so I have been told) and have replaced a head gasket on my 1965 220se, engine no. 127 982 22 013 972 (injected model).

I think I have done everything right, but am unsure if I have set the valve timing correctly. Havn't started the engine yet and have removed all rockers for fitment and adjustment.

Is there a way to tell if the valve timing is correct without learning the hard way? Are there markings? What is the 60 degree after TDC mark for? Does this mark have anything to do with it?

Any input would be greatly appreciated!!
