    B Head or is it a Model B Head?

    Sometimes people ask about a B head, but they aren't specific whether they mean the Model A high compression head with the "B" cast in it, or are they talking about the Model B engine head with the large "C" cast in it. Besides the letter cast in each head, they are very easy to tell apart by the water pump.
    The Model A head with the "B" cast in it has the regular 4 bolt Model A water pump and no coolant outlet as part of the pump.
    The Model B head with the "C" cast in it has the 3 bolt water pump with the coolant outlet cast as part of the pump.

    When I bought my truck it had a B cast on the head. I was told that was a Brumfield head. The water jacket was cracked, so I went about looking for a replacement only to discover that it wasn't a Brumfield and that Brumfield quit making them. Settled for a 5.5 Snyder head.

        Model a head
        by Travelair 3000
        Anyone seen a head like this with this plug in the water gallery? It is steel. This is on my 31 Roadster.
        Someone suggested an industrial head.

        Thanks...

        Markings on Model A head

        Putting a rebuilt engine together.
        This head is standard, but must have been aftermarket.
        Note the different castings....

        Help identify head
        by Eric
        Greetings y'all..... I am trying to identify a head that I pulled off of my A motor. More idle curiosity at this point, as I just installed a Snyder 6-1 head... Is it just a stock head??? I see no markings on the cast.

        Thanks ahead of time...

        BTW... the new Snyder head runs GGgggggoooooooodddd!!!!

        engine water outlet
        by Art Ebeling
        With the Model A and the Model T parked next to each other it is interesting to compare them to each other. I do wonder why Ford put the Model A water outlet on the head using two head bolts instead of being detachable like on the Model T head. Art...

        cracked head
        by thom
        This morning the cylinder head cracked on our '28 coupe. I cranked it and drove off in it without checking the level in the radiator, but I had checked it last evening and it was good. There was no sign of leakage under the car or water/coolant showing on the oil dipstick. Shortly after startup, I heard a whistling sound and stopped to check it out. There is a crack across the head about 2/3 back...

        head removal help
        by fmr187
        Anyone have any tips/suggestions/secrets for getting the head off the block? I have a motor that has been sitting in a barn for many many years. And I started to take it apart. The head nuts came off easy. But how do I go about lifting the head off? It seems that there is corrosion between the head and the head studs. I have been putting penetrating fluids down the head bolts for 2 weeks now. Some...

        Which cylinder head do I have
        by fried okra
        I see there is the stock 4.22 compression head, the 5.22 police head and a 5.5 aftermarket head and others too.

        is there any way to tell which compression cylinder head I've got while it's still on the car?

        Specifically from an external appearance perspective, not pulling the plugs and doing any kinda testing really....

        High compression head installed.
        by AzBob
        New Prus 8:1 aluminum high compression head installed. Can maintain 35 mph on hills I used to have to downshift into Ruckstell with. A noticeable improvement in performance all around. The aluminum head weighs 12 lbs. The old 3.98:1 cast iron head weighed 28 lbs.

        Water Pumps
        by dmdeaton
        What is up with new water pumps? The flange on the pumps is tight enough in the Head bore that something needs to be relieved. I don't know if its the head or the water pump. I have a couple new heads, and both fit the same. I haven't measured either yet, but will when I get time. I also have 2 new pumps laying around and they both are tight. I have an old stock head here at my shop and I will measure...
