As far as longevity on those, guys still do cam swaps in them today and reuse the original lifters. My sons 89 5.0 engine has never been apart and has 256,000 miles on it now. Quiet as a mouse and doesn't use a drop of oil. Bone stock and just came off the chassis dyno where it made 231/277 at the tire. Now he wants a cam upgrade and I'll most likely just stab the original lifters right back in it.
THAT HAS BEEN MY EXPERIENCE TOO WITH CRANE/CAMSHAFT MACHINE COMPANY.

Harvey Crane had issues with the other two guys who took the bail-out money but "F" never took that money. I was very good friends with Don Hubbard, a Crane VP and Glenn Corwin a true blue Pontiac Guy. RIP Guys.
Crane also owned the Wolverine "Blue Racer" company (I was a WD for the Parts) and sold a lot of Pontiac parts at that time. No F stuff though, all GM stuff. CMC is still in business. When Harvey died, the Crane side and the employees, Don Hubbard retired and Harold B went to another company.

Not absolutely sure on the other two guys failure rates but do remember that there was info floating around that Keith S would be able to answer as far as the Roller Cam durability.
