    Not to lift just the heads; but the whole engine!

    Those really look like they are undrilled bosses for coolant fittings. Plus the unusual threaded center water outlet means there was cooling system modifications on these heads.

    Probably part of the casting or someone had the right idea for lift points.

  5. Swedish torpedo boats had three Isotta-Fraschini W18:s, which were pre-heated with two Ford flatheads. Could these heads be from a similar military application? Unfortunately I couldn’t find any photos of the engines.

  7. At any rate someone probably paid a lot of money for them to be cast in the first place. Paid for the; engineering, mold making, casting, and machining (which is probably normal, can't tell from the pictures) for a very small application. I would look further as they could be very rare due to the casting difference.

    Discovered a 2 Ford engine use...a British landing craft/ assault barge, I think the one referred to as the LCA, landing craft armored. Sort of a LCVP with a hinged lid.
    I just remembered my copy of Ford At War, book by Enfo.
