Best to install in the head and measure at the valve. Again, when you take away the base circle and don't compensate in lash, the dynamic valve lift will be less with a regrind. (not just hydraulic lash to keep contact, actual lifter in collapsed position)

Again, I would have dismissed this as a weak engine, but it was collaborated by Dave. He put regrinds in his shop e30 and he lost a few HP.
