Will b1 throttle body work on a1 intake manifold?

Buddy of mine broke his a1 fitv, I only have a b1 fitv + throttle body. I had the idea of him putting the broken fitv back on as a block-off plate, and running my spare b1 fitv + throttle body…this is on his b18a1 motor.

Will the b1 tb/fitv work on his a1 intake manifold?
