I was able to find the lifter from the wasted lobe and looked more closely at it. It looks like the scarring is all in one direction- like it never rotated.
I will change to another brand with a lift no more than .500 and clean up my lifter bores. No cam lube on the sides!
So have you pulled the motor down after losing 2 cams? 
OR ...at least drop the engine oil pan. THEN put a magnet in there to collect the rest of the "trash".

How much lifter rotation is there in say spinning the motor over one revolution?
I mean say you mark the lifter and the bore....and you turn the motor over one revolution....how far should the lifter turn from the mark on the block?
not much , but the lifter should rotate close to a 1/4 turn , it doesn't rotate till it goes over the nose of the lifter lobe . I usually mark all lifters and all pushrods and rotate the crank untill I have seen 1 full revoution of all the lifters and pushrods .
