I have a set of Y-block exhaust manifolds and cross-over that I need help identifying as to fitment. The numbers are EBU-9430-B and EBU-9431-C. They were on a 1954 256 cid Mercury but the Mercury parts manual uses the prefix EBY for 1954 instead of EBU. I am guessing that they may be for a 239 cid, but I cannot translate the U identifier. Help?

ENGINE SERIES IDENTIFIER -

EBU 1954 239CI PASS CAR (DIF)

EBV 1954-55 239CI TRUCK ENGINE (CLV)

EBY 1954 256CI FORD PI - 1954 MERC - 1954-55 TRUCK (CLV)

That ID SYSTEM was used before FORD went to the P&A SYSTEM 1957-58 on where the CASTING ID NOS Prefix were four character,

as far as fit goes they will interchange with all y blocks

But not necessarily into different vehicles, due to the fit around other parts under the hood.

Now you wonder if it has the correct engine ...

Thanks for all of the comments. I can now be fairly certain to market them as 1954 Ford 239 while still fitting a 256, 272, and 292, depending on which heads match with the size of openings.
