Cam checking v-blocks

I usually try to not rush into projects so I can think on them awhile but have any of you guys made up a set of V blocks for checking valve lift. Trying to avoid putting blocks on engine stands to check valve lift on a few cams. Something of course portable that I could easily check out some big and small block cams I’d like to sell. Just to double check what I’m seeing with calipers and mics.
