Where do you think you obtained them from. Surely that might give you a clue.
They could be reasonable valuable (although without the manifold and aircleaner assembly less so) as there weren't that many models that came out with them standard. They were a popular hot-up mod in the 70's/80's - someone with a 180BSSS upgrades to twin webers, so sells their twin SU's who puts them on their non-SSS 180B for example. Even better if you ported the head and installed a warm cam (say 72deg). Of course ditching the L18 in favour of a L20 was also popular at the time. My 1600 ran a 74 deg cam for a while then 76 deg on avgas later on in life 2.1L L20 block. Some of the rally guys were experimenting with 78 deg cams and BMW grinds.
It was in with a heap of stuff from an old guy that i bought.
