Those work, that is an interesting manifold.
I can't tell what metal the manifold is made out of. I'm guessing it's cast iron, the welds look good on the cover plate.
The outboard runners are divided and there are ports(?), heating(?) under the runners? original?
There's enough throttle body to fill the runners plus some.
My guesses

Its an aluminum intake manifold. Both divided runners and heating are original just being welded the centre stock carb hole and the new tbi plates. This manifold came on late 250's carburated engines on Brazil, from 1990 to 1992 I believe(not sure about the models).
As for the TBI's I really don't know if they are enough to feed the 250, as they are used in smaller VW 4 cyl engines. That TBI is used by itself in a something around 110cid engine. So two of them would, in theory, fill 220cid. Missing 30cid then...
But don't know. Can be good for torque maybe.
