I was just looking to get data for comparison, not how-to setup the rockers.

For example, the minimum in/out motion of the rocker tip on the valve stem should occur when the rocker pivot is 1/2 the valve lift distance below the valve stem tip (in the same plane as the valve stem.) This would make the rocker/valve stem tip 90-degrees (again in relation to the valve stem angle) at 1/2 lift.
This means the ideal rocker stand height will vary depending on the valve lift you choose.
This does not account for where the rocker contacts the valve tip, that would have to be built into the length of the rocker arm or changing the in/out location of the rocker shaft.
