    But with this came some bad news today- her head is cracked through to the exhaust ports. As such, it is beyond repair.

    So now, I'm stuck with knowing what to do. I'm inclined to put this project on ice until I can find a new head, because putting any other Series engine in instead, it would seem to me, comes with the risk that it too may be not so good either.

    So if anyone knows of a head (2 litre spread bore) that I might source, please let me know. In the meantime, I think I'll need to bring Matilda back home as she is currently taking up real estate in Mick's shed and that doesn't seem right either.
    In the restoration game nothing is beyond repair, it comes down to how much time effort or money you want to put into it. As said before as to location of valves, the head only has one and it is the intake one.

    A competent machinist could tap some overlapping dowels into the crack, welding is also an option. If you do a hunt around you will find other trick ways of fixing cracks in cast iron.

    Problem I see with the diagnosis is that the exhaust valves are in the block, as noted. And cracks here would not be all that unusual. Since the exhaust valves fro memory have separate seats, it seems to me that a welding repair is possible, although it would be a specialist job.

    If it is the head, then it should be possible to find a new or second hand one. since as pointed out they are all the same.

    Oh wow..... Thank you so much Keith....and to everyone else who has offered comment, help and suggestion here....I might have the detail of the crack wrong, as I have had a deal of distraction lately, but the fellow doing the work is very experienced and has rebuilt Rover engines for years, even for the old Ipswich Rover dealership....I'm sure he is justified in telling me the old head is shot....but I'll run these comments past him anyway....appreciate everyone's knowledge and input.

    But Keith - that is just such a generous offer ....if you have a head that will work for my engine that is simply terrific news....I'm rather humbled, all over again, by this kindness and by that of all here....it's moved me to tears ......I'd be very appreciative to work out with you and Dave/Paul how to get hold of what you can offer me....I'll get back to you....thank you again.

    So the same head fits all engines 1.6 and 2 litre siamese and 2 litre spreadbore.
    I think the ones I have are from a 1600 but if one is OK you are welcome to it.

    Keith, you are a credit to the club. Thanks for being so willing to help Dan. We are not worthy.

    Cheers, Mick.

    No Problem. Happy to help out.
    I am no head expert, how hard are these cracks to see?
    Are they visible with the naked eye or do they need testing etc.?

    Well - no one noticed the crack until it had been "bathed" by the engine re - builder, so I suspect they might be hard to see.....perhaps, if we initially took a few different heads, Craig could check them out and hopefully find a suitable one.....I could then at least tell you that the others are also fine (or not), and return them to you.

    Sounds like a plan.
    I can get them to Wondai if Dave would rather pick them up there.
    One of our rifle club members is going to the Wondai Prize meet and could take them.

    Well Scallops has a choice of four heads.
    Cleaned them up a bit and cant see any visible cracks though that does not mean much.
    As you know the exhaust valves in the block have hard seat inserts but the inlets are just cut into the cast head material. these will have to be recut, head skimmed and some of the threads tidied up with a tap.
    Good Luck.
    Keith
