Uncle Tony says Gen III hemi has inherent lifter lubrication problems. Agree?

Does anybody know if the Magnum roller motors had lifter problems? I have a 360 magnun from 02 with 140,000 miles I bought used and haven't tore it apart yet, word was it came out of a Van.
Never heard of the 5.2/5.9 Mags having cam lifter issues. My dad had a 94 he put 334,000 on before it ate a head gasket. Never was opened up.
