Magnum roller lifter question

Hey All,

In the process of getting my 5.9 magnum broken down for a trip to the hot tank etc. The rollers on the lifters feel good. They look okay too. I was thinking about running them until I talked to Tim over at Hughes this morning and found out I can't replace them w/o the heads coming off.

Hrrmmm.... Engine had 110,000 on it and they weren't tapping. But the internals of the engine are a bit grimy and it looks like the owner may have skimped on the oil changes (based on blow-by, not wear. There seems to be very little wear)

Has anyone taken them apart and cleaned 'em? Good bad? Tim says the snap ring is directional. Any other tips?

Or should I just bit the bullet and by new ones.

Thanks,

CE
