Belts, pulleys, and spacers.
Only one drive configuration was used on the shovelhead belt drives: a 33 tooth front pulley, a 70 tooth rear pulley, and a 126 tooth, 1-1/2" wide drive belt. However, using belts and pulleys from later models or the aftermarket allows some slight alteration of final drive ratios, see also here
