I have a brand new Schrick camshaft for all M103 motors. Here are the specs:

Chilled cast iron cam

Intake:
272 degree
7.7mm cam lift
11.5mm valve lift.
intake opens 24 degrees before TDC and closes 68 degrees after BDC
valve lift at TDC 1.1mm

Exaust:
268 degree
7.6mm cam lift
11.3mm valve lift
exaust opens 66 degrees before BDC and closes 22 degrees after TDC
valve lift at TDC 1.0mm

You must use rocker 103-050-10-33 since this is a chilled cast iron camshaft and MB went to chilled somewhere between 1988-1990 or so. That part number is for the chilled rocker arm. Best to check. You can of course get them at the dealer if your motor doesnt have them. Also included are 12 new schrick uprated valve springs. $620 shipped insured ground in the 48. I paid over $850 6 months ago for these parts and they are no longer available. Let me know if you have any other questions.
