rough idle

1977 450sl 40,000 miles. i have had this car for 2 years now, bought it at the denver auction thru kruse. at that time it had 34,000 on it. at cold idle it is pretty smoothe as it warms, the idle becomes more rough not awfull but not the way a mercedes should run. on the road it seems smoothe.there also is a little lifter noise or something on the right hand side. from previous service records the right hand cam shaft was replaced at 25,000 miles. is it possible the lifters, rocker arms, and cam need to be reajusted. could they be out of sinc??

thanks again
