    Yes, that’s the part that Colin mentioned in the second post. It is BSP as everyone is suggesting.

    Now to get them out….

    Just to confuse the issue 3/8” BSF is 20 threads to the inch and 3/8” BSP is 19 threads to the inch. I removed another plug from a spare head and as I can’t find thread gauge I tried to compare to a Pickavant thread restorer file and it seems to be 20 tpi.
    This could go on forever

    Series II listed as 3/8" BSP (in the parts book), Series III as 3/8" BSF (when you searched the part number, wasn't stated in the parts book).
    Someone has got their BSP & BSF mixed up

    G'day All,

    Agree with Colin on this one. I measured the sump plug for a series 2a and the thread is 3/8 BSP 19 TPI parallel thread (major diameter 0.653") and seals on a copper washer. The sump plug screws into the port for the heater tap at the rear of a 2a head.
    The plug for the heater tap and thermostat housing is 3/8 BSP parallel thread and seals with a copper washer. Our vintage of British vehicles use BSP threads and adapters in the cooling system. They use 3/8 BSP fittings because the bore allows 1/2" tubing and hose.

    Looks like all the British part supplies has got their BSP and BSF mixed up. The classic typo maybe!.

    Wayne,

    Hello again - you win the coconut on this one.

    I happened to be walking past the project earlier today and gave your suggestion a bit of thought. So, I gave each plug a solid tap with a small hammer and large brass drift plus some more Innox. Applied the six sided socket to the rear plug and it came free immediately. Same procedure for the front plug and similar result.

    Both out with no apparent damage to either man or machine.

    Cheers,

    Neil

    Hello again.

    For a bit of closure on this task - I fitted the hose connection points to the head and then proceeded to complete the plumbing.

    A new discovery of the apparent oddities between Australian and British assembled Land Rovers scattered here and there about the vehicles. No doubt an artefact of the local content rules of the era.

    In this instance the outer diameter of the UK-sourced head hose connectors and that of the locally installed heater core is different - I think the latter may have even been Japanese. So, after several trips hither and thither to auto shops, my usual nut and bolt place and Pirtek I took on the connection task with the help of a couple of reducers, more hose clips than I originally wanted to and - after several visits to and from Repco and Supercheap - a piece of twisty hose with a couple of right angle bend sections of the right inner diameter.

    It came up well enough in the end.

    Cheers,

    Neil
