Default cam lobes going bad?

My cam is a SFT. Earlier this summer I found the lash was opening up on some of the CC roller tip rockers. I checked the cam lobes and lifters and all looked fine. I replaced the rockers with HS 1.65 rollers and still have the same problem.
Ihave driven it less than 50 miles and have had to readjust the same 3 rockers 3 times now. This last time I noticed what looks like a moly lube[dark gray] paste on and around these same rockers,which are the intakes on 6 and 8 and the intake on cyl. 5. The tip of the pushrods are also wearing,flaking.

So before I tear into it again, does it sound like the cam/lifters are wearing or maybe an oiling issue? I do have a zinc add. in the oil.
