I guess I don't know what "NNBS" covers
I bought a 2013 Silverado intake manifold because I thought it is a NNBS, and the internet says that a NNBS manifold is the same as a TBSS manifold.
So will the fuel rails and other stuff that I can't think of from this rectangular port manifold work on a TBSS manifold?

Actually rectangular, running same intake on my 99 and you need fuel rails for that intake or aftermarket!!! The injectors go in at different spots onthe intakes which in turn moves the bolts to opposite side of the rail, if you have cathedral port heads you need a cathedral port intake.... The rectangular ports i do believe are taller than the rectangular ports....
