Can anyone recommend the best manual to buy with the best technical information like torque settings etc . Cheers.
Not sure about torque settings, most of these things are tight vs v tight with normal size spanners and relies upon mechanical sympathy (steel into aluminium vs steel into cast iron, fine thread vs coarse thread and on tinware you will find lockwashers or star washers are your friend).
To have good coverage I suggest BSA (DW Munro) Sixth Edition:

The Haynes Manual (BSA singles 54-61):

These are excellent little books too:

If you have to get one book then the latter is the one to grab (there is one on ebay now that is the pic I linked to.
The new Haynes manual for the Pre-unit Singles seems to be a scanned and computer printer produced book. It's okay but the photos are not very clear. If I'd known this, I would have bought a used one from Ebay instead.
Thank you I've ordered that last book cheers .
