stupid long or shorter headers?

[WSSix]

In order to build headers that will clear everything on the car and not drag the ground, it appears I'm either going to have to go rather long with the primaries or go short. By long we're talking 40-42 inches and short would be maybe 24-30 inches at best. I know from my reading that the prevailing thoughts are longer primaries are better. I guess the question is are they really worth the effort? I'm leaning towards longer primaries just because I think it would be fun to build and look great. I'd also hope it would help make more power. I have no doubt they will be harder to construct than shorter headers. I don't have enough knowledge or experience to say if it's worth it though. Thoughts?

Thanks
