I looked into this when doing my CA conversion as the 3-pulley was touching the bottom of the radiator. The options I found were pretty much what has already been stated above: 1) cutting the stock 3-pulley down (this is virtually impossible and I would suggest that even if you got it machined down it would be a risk of falling apart) 2) use an EXA 2-pulley. 3) buy one of the 3-pulley billet ones off eBay, which could be machined down to a single....but these are not really harmonic balancers. These have no dampener in them. 4) buy the Ross full metal jacket single pulley. Pretty expensive at around $630. 5) buy a powerbond under drive 3-pulley and have it machined down.
I did option 5, but only had it machined down to a two pulley. This gave me the space I needed and still kept the integrity of the balancer. So far so good...but I haven't had my engine at high revs yet.
