LS swap manifolds/headers

[Wscott9689]

been doing a little research on manifolds or headers that are not so expensive. im planning on either a 5.3 or 6.0 for my bagged 68 2wd. also which mounts? can you use the truck manifolds if you modify stock towers or use the ECE or POL mounts? any alternative headers that will fit with little or no modifications? long tubes will be ok as long as they will not be below the frame rails. thanks for the help!!
