the lobes are not recoverable
take the camshaft to a shop to measure it
but if you main bearings are worn and the camshaft has wear
scoring plus the wear on the followers, you need to do some work.
mercedesengines.com carries the camshaft with a matched set of bearings, plus all the followers.
Mark Luna just did his.
that is massive wear on the followers, like you are not getting oil to the top, you probably have wear on the followers studs and valve guides, possibly clogged oil delivery or weak oil pump..
i am rebuilding my engine right now, 250C M130 and the head got new valve guides, machined the head, valve seats, the followers, springs and studs are good for me. the camshaft has minor wear and it will stay as is until the next time.
