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?
