Did you mic that cam to be sure it is bad? How did the lifter look? I have had good luck with Hughes cams over the years.
I haven't miced the cam. The 340 cam has two lobes that have pitting on the nose of the cam. one of the lobes shows wear all the way across the lobe with pits that will catch you fingernail. The bottom of that lifter looks to have been hit with a tiny needle scaler. The other lobe is just starting to pit. The rest of the lifters and lobes look perfect.
The 408 had EDM lifters in it and has several lobes and lifters as I described above.
