Cam & lifter set up for 190E 2.6

I'm looking for the torque specifications for the cam shaft bearing cap bolts and what shims I should select to get the correct lifter/valve clearance.

I'm helping out my father in law on his project car which had a terrible rattle which we found to be an excessively warn cam shaft. I now have a good second hand one, but needed some info on putting it back the right way.

Any help would be appreciated.

Cheers
