Is my logic off when I think that valve alignment's main objective is to make sure that casing ports and valve holes are perfectly aligned so the horn has its optimum air flow? To accomplish this pads and guides are used. Properly done this should leave the valve buttons at an equal hight. I would think that when this is done correctly the nature of the horn takes over as far as slotting and pitch. This being said, I don't see why valve alignment is so difficult to do.
