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?

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

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.
