If your pushrod needed to be sunk .040" and the pushrod stayed the same . Mulyiply that by the rocker ratio. You do not think that will change the rocker arm to pushrod angle , then at .090" even more. Did you even look at the wipe of the rocker arm on the valve stem. How that relates to the rocker angle. Your post was harsh. They are good people , but have not layed out or discussed what is happening.
