well after researching for a while on the boards and reading some posts where some guys didnt have any problems bolting their prochamber to the bbk longtubes, i went ahead and bought that combo, and found a rude awakening whent he prochamber was a couple inches too short on one side, or an inch too narrow (either way it didnt fit) i tried bending it but that only threw off the hangers and it was a nightmare, but i am determined to make this fit, so im going to take the chamber to a shop and have em fab up a new pipe that will fit to the headers. 
this was a really frustrating weekend, i expected everything to be done in a day, but after the clutch job, rear main seal and headers went in, the prochamber ruined my whole weekend and week until i get it to the exhaust shop. so just a friendly reminder, on an 89gt with chrome 1 5/8 into 2.5 collectors bbk headers, do not just "bolt up" to a 2.5 in mac longtube prochamber. but i am going to make an exhaust clip of it after its all done. 1 5/8 bbks, 2.5 into 2.5 in prochamber into 40 series flowmasters with 2.5 tail pipes.
warning: prochamber + bbk longtubes = no fit!

I figure it would have to be for long tubes. Otherwise it would be several feet too long instead of a couple inches short.

Heres the deal...
Mac long tubes and BBK long tubes are different. They end at different locations. You have a prochamber for Mac LTs. Im not sure if they make one for BBKs, but they are different. You did not research it enough, because I would have informed you of this if I had seen a post about it.
