ok well your altering the lift ratio by changing the fulcrum point... the farther the adjuster gets away from the shaft center line the closer to 1:1 the lobe lift to valve ratio gets...
so by moving the adjuster closer to the shaft you increase the valve lift...
for a jig i would weld a peice of the shaft to a peice of plate... then make a adjustable arm that holds an adjuster... cut it up and install the adjuster into the adjusting side of the rocker... now line up and weld...
