Never seen such a worn lifter! In all of the more than 700k miles and about 14 B20's in 140 series cars have I ever had a lifter wear, not even a bit beyond adjustment from cup wear. Now the bottoms of the lifters are a different story.
The only way for that to happen is for the case hardening of the lifter to wear prematurely or a bad lifter that never was case hardned properly. This is a common problem with the older B18 cams where the lobes go quickly after the case hardening thins down.
Were these new lifters? Volvo lifters.
