[GUMP]

I have a friend that I believe builds pretty good stuff post photos on Facebook of worn out flat tappet lifters and cam lobes that he encountered during break-in. I have read a lot about this of late. Is it really time to allow rollers for all combinations in stock due to inferior parts? Or, are the cams victim to other factors related to the valve spring and solid lifter rule changes?

To be clear, I have no current dog in this hunt. Everything that I own and am currently working on uses rollers.
