Need to make space for screw in studs for roller rockers on your factory heads? Simply attach the boss cutter to an arbor press with the included adapter/guide, mount your cylinder head boss underneath the blade and cut away. Please note that the cylinder head may need to be angled correctly before cutting, and the finished cutting area should be at least the same diameter as the screw in stud hex nut flange area.
