Cool. If you do want to raise the handlebars you'll still need a stem riser (not riser bars) or a new fork with an uncut steerer (cleaner look but $$). You generally only want about 3mm between the top of the stem and the top of the steerer tube, much more and the stem doesn't have much to clamp to, much less and headset pre-load cap can't do it's job. The Park Tool website has detailed guides on servicing headsets and lots of photos. But, in short I wouldn't add spacers to raise your stem/handlebars.
