Bingo, you got it...

The correct rocker arm geometry WILL result in the least amount of swipe across the valve. Setting the correct lift is not getting the correct rocker arm geometry. You can check for correct rocker arm geometry without even having springs on the head but do use the checker push rod to get you the correct length. But remember that is the correct length unloaded. Some where along the line, you will need to assemble the head to get the correct length LOADED. The length doesnt change, but when loaded, the pushrod may no longer be that length.
