I have bassani longtubes...the steering shaft goes in between the primaries. I have a c-4 with explode proof bellhousing and they actually fit. Each primary comes loose from the collector and head which is the only way it is possible to get them in. I didnt have to "hammer" on any of the tubes.
i had the hooker super comps with a C4 and had to run an aftermarket steering shaft but that was it. and if your running an auto, i had to take my motor mounts loose to get them in. its also a very close fit with the stock starter but i ran mine without problems.
Have had MAC 1 5/8" longtubes no fitament problems, MAC 1 3/4" long tube no problems, and just installed some Kooks 1 7/8" long tubes and they fit great as well.
