As an ex-disel mechanic, I can tell you that it is vital that you get 'em checked and if required, adjusted.
It's a long winded job on any engine and a lot more so on a 6 cylinder diesel. It's also a job that you can get wrong very easily - with catastrophic results on a diesel. Bent con rods, burnt vales, holed pistons, bent camshafts (OHC), bent pushrods (OHV) just to name a few,,,,,,,,,
I know of one very infamous one that I myself stuffed up when I was
young and in a hurry and took a chance on it,,,,,,,,,Cost a heap of dough that one did.
If you're not skilled in this area, then get someone that is skilled to do it - and make sure it is actually done. Try making little tell tale marks around the rocker cover gasket joint ( a bit of paint etc) etc,
check out what needs to be removed to get the rocker cover off and take a picture of it.
Check it later to see if it actually has been removed etc.
A good wipe of the rocker cover with an oily rag can make it look like the job's been done,,,,,,,,,,,,,to an inexperienced eye.
Bottom line - GET IT DONE.
