thanks Frank and forum

so, I am sure the previous owner had a bad camshaft on the right bank and replaced it with a camshaft( number 71) possible forma W126 , 380 model.

I am looking for a set of cams with the numbers 00/01 in the meantime.

The question I have, will a set or 70/71 be a workable solution if I replaced both cams with this option.

I also have a set of 08/09 cams. any thoughts on using these alternative sets to the 00/01. will it affect performance negatively?

if the answer is " do not use them" , then I will find a set of 00/01.

appreciate your comments.
