This will work, but, it's not the best method. The rocker shaft and
valve positions are fixed. For the optimum rocker nose contact with the
valve stem head, the distance between the rocker bore center and the
contact point of the nose should also remain fixed. There's also the
additional problem of weakening the stock rocker by additional boring.
Ideally, the ratio should be increased by decreasing the bore center to
pushrod point, because that end of the rocker is made to operate with
some misalignment. This could be accomplished by overdrilling,
rethreading and inserting a flanged, threaded plug, staking that, then
drilling and tapping for the necessary offset. The same proviso about
weakening the rocker at a stress point still applies.
Cheers.
