TTI SHORTY OR LONG TUBE ?

I finally decided to go with the TTI headers. Now all have to decide on is to get the shorty or the long tube headers. Ive hears so many good & bad points on both headers. Cant make up my mind. I have a 67 barracuda 360/408 factory cast iron heads. Manual steering. 904 trany Stock front suspension What do you guy and gals think ?
