School me on re-using a new(ish) camshaft

If the lifters were not numbered to their corresponding lobes they were run on, buy a new set as mentioned, then break the lifters and cam in just like you would a new set.
Why the change in attitude for this thread? Awhile ago u said there is nothing wrong with using used lifters over even if they were not going on the same lobes. Care to clarify your responses? Just curious as this is totally 180 degreeā€™s from the other thread. Kim
