| What's "voo-doo-like" about aligning the valves? It's one area that can be seen when it's bad by depressing the 2d valve and observing how the valve does or doesn't line up with the ports. When you consider how different a .462" horn can feel compared to a .459" horn it's easy to understand how an 1/8th inch misalignment (.125") could impact response.
