H22a header

[defect]

I was very curious why the primary runners of most 4-1 headers for h22a are really long
comparing to a tri-y design.

Is there a reason for this? I was thinking of purchasing a tri-y and using only the primary runners and make it a 4-1. Would there be any disadvantages to doing this besides wasting time and effort?
