Cams to be used in 1979 300D

I currently own a 1979 300D which has a "worn and scorn" cam. The rocker arms near the front are worn also. This engine has the "00" cam installed. I was given a newer cam and rockers by a friends dad. It is the "05" cam which is the newer "hardened" cam with higher lift. Can this cam and rockers be used in my 300D with engine: 617.912 1207. Too the newer cam has the MB Emblem stamped in it along with the 617 05 between the number 3 and 4 cam lobes. Help someone......Kent?
