Thanks for the terrific advice, everyone!
Many thanks for all the terrific advice. I couldn't do it yesterday as I was missing the correct Whitworth sockets, so have ordered them, and all going well, will give it a go next weekend. I did get the brakes all sorted and well bled, so made some progress.
thanks once again to everyone for their support and advice.

I should not have worried - all went super well
I don't know why I was so anxious about there head bolts. Armed with a lovely new set of Whitworth Sockets from AGSPares - half normal price at the moment and terrific service (http://www.agspares.com.au)
everything went super smoothly and had the head off in no time and with no problems at all.
I'll clean it up and strip it down tomorrow.
Thanks for support and confidence you all provided.
Lovely to know that we have such a great group ready to support us all as we bring our ancient Land Rovers back to life.
regards and thanks
