The M102 did come with a twin cam when modified with a Cosworth head but
standard is single. However due to design the camshaft 'vibrates' more than
in other Merc motors, as an example the M103 does not eat timing chains as
much due to being more 'balanced'.

The M102 does require chain replacement on a more regular basis.
Is that a twin-cam? I'd expect them to be more hard
on chains as well. I'm guessing you can pretty much
look at the chain path and figure how long one of MB's
chains will last. (Ignoring defective designs like
the single-row 3.8 and defective materials like those
bad chains in the 90's.)
