Each header has 9 pieces. Two tubes on each side go through the inner fender and the others down by torsion bar. Made them slip tubes, just need to use muffler paste to make sure it seals. We put passenger side four tubes on and then just 1 and 3 when installing long block. Once I get the engine in I attach 5 and 7. Then add mid-pipes on all 8 into collector. When starting I just put the block in and took the heads on and off as we made the pipes. Was hard but after done you do feel good about it. Now if you go with after market front suspension with coil overs then it is much easier. Hope this helps.
