Maybe I can help, the "Wedges" are a pair of machined aluminum shims shaped like the base of the handlebar stanchion, that is angled at 6 degrees, with the thin side nearest the steering bearing. They go between the base and top-clamp and the wedge shape tilts the stanchion toward the steering bearing which elevates the handlebar ends about an inch and makes them more horizontal. It also brings them closer to the driver a small amount. The effect is to remove some of the compound twist in your wrists. They come with special washers made with the same 6 deg. angle that allows the bolt heads to bottom correctly. They don't affect the hydraulic hoses much and can be used on top of riser blocks. They do add 1/4" & 1/2" to the required bolt length. Murph is supplying them and he also has longer bolts, so tell him if you have riser-blocks or not.
This photo may help, it shows the difference in handle-bar orientation with the wedge:
