Seems like it's always about fit... be nice to have the advantage of everything bolting in!!
On my "stock" suspension Bronco back from '76 till about 1994 I ran long tubes, never hit a thing on the headers when wheeling.
Converted to soft long travel springs and all of a sudden I could go more places and I hit my headers a couple times... had some major dents in them.
Swapped over to short tube headers and never hit them again when wheeling...
Moral here for many of us is we run what works, fits and what isn't heavy (cast manifolds), and what doesn't crack (stock 302/351 manifolds)
1 1/2 years back with more suspension mod's I still run the same JBA shorties but have had to cut the collectors off both sides to make them fit. My Dana 60 yoke had 1 1/2" of interference with the shorties... and that was before the 90deg elbow was welded in ...PSD downpipe fit perfect there so both sides are modified, re-welded and re-coated. Couldn't even imagine trying to work around long tubes now...I'd have to run them out the hood!
IF you can fit them, they add some HP/torque no doubt
