May be more identifiable when you pull them out and snap a pic

I bought my 1st set of comp lifters from dave at SD in 2012, had the engine/car running in 2013.. it ran great but had the notorious hyd roller ticking, dave suggested adding some seafoam to the oil to see if it would clean out any debris from manufacturing but it didnt work.
He replaced the lifters under warranty with the "new" S comp lifters that came out in early to mid 2014, replaced them in late 2014 according to my notes. So these lifters werent the shavers, look like my originals from the pics, either johnson or morel.
Is it possible the lifter wheel wasnt hardened right to cause that damage? Pretty sure the OF cams were billet, thats why they require a poly or brass dist gear. Bearings could be bad too but still roll ok under no load?
