The distributor/oil pump drive problem is one hardware issue, another is improperly drilled rear cam journal starving the top end for oil. AFAICT these issues weren't confined to Comp's cams; there was a run of poor-quality \6 cam blanks and pretty much everyone got them, though I don't know when it started, when/if it ended, and details like that. A heavy-duty oil pump and drive gear will not save your bacon if the cam's drive worm is wrong—something's gotta give (get shredded up) and the damage won't be pretty.
Comp-specific issues in principle: lazy, braindead use of Chevrolet lobe profiles sold as "upgrades" for Mopar engines, throwing away the big advantage of the larger-diameter Mopar lifter (which allows for a steeper/faster lift and drop)
Comp-specific issues in practice: I have seen more failures of their 252° "upgrade" cam run right (let alone running well) than I have seen successes. Some people seem to make it work, but many people don't. Seems like it's difficult/impossible to find a valve lash setting that makes the engine run correctly both cold and hot without making noise. All points back to Comp's slackaѕѕеd use of cam lobe profiles incorrect/unmatched to the rest of the engine.
I have no knowledge of Comp's other \6 cams besides the 252, which is (in my view) a big enough POS to steer me far away from the rest of their stuff. Maybe they make some good \6 cams, but their continued marketing of the 252 warns me off.
I would if I could, but I'm not qualified to make a specific cam recommendation for your turbo motor. But there are enough people around here and on slantsix.org who have put together good-running turbo \6s that good guidance ought to be available.
