F22B1 or F22B3 engine?

[repeated_love]

I have a 1994 Honda Accord Exi 2.2L automatic sedan.

Am buying parts to get it fixed. The suppliers are asking if the engine is F22B1 or F22B3. I am not sure which one I have, is there a way to tell from an engine plate or something else?

A few years back the engine blew and I had a replacement engine put in as well. The engine still has writing on it that says RA1, F22B.
