Tim, all of my camshafts are from Comp. I don't have any issues with them. I hand pick the lobes per engine, they grind them, and we're on our way. With maybe Bullet as being an exception, Comp has the most lobes to choose from, which makes it much easier to nail down an exact camshaft profile.
Your issue was with running a solid roller lifter on a block that's not drilled for lifter
oil galleys. It wasn't Comp Cams' fault.
