https://youtu.be/OqmCeX88-JQ?si=MMJKr1V3JwsXXQo8Lots of talk about this on Speed-Talk in the last few years if you Google it. Mike Jones aka Cam King on there appears to have good inside knowledge on who makes what.

Some might, but I'd only trust a direct call to the cam company for that answer, or ask Hylift who they sell products to. The internet is full of rumors on where parts really come from so make some phone calls first. Lots of reboxed parts and poorly made parts in circulation these days and lots of finger pointing going on out there.
You have to buy these direct, or find a smaller vendor like Hughes who sells them exclusively. I have a set from Hughes and on the contact surface you can see the grinding cut marks. If you buy lifters from somewhere else and they are very smooth and polished looking chances are they didn't come from Hylift.
Also towards the bottom of this pdf they discuss lifters with different bleed down rates depending on your cam lift and spring pressures. People often complain about noisy lifters with bigger cams so maybe they have ones that cure that issue?
