Torque setting for con rod nuts?

[Ben]

Need the torque setting for the connecting rod nuts. In the Haynes it gives a setting for 'big-end bearing cap nuts', which is 20Nm and then 70 degrees. But I thought big end bearings were the crankshaft bearings. There isn't any other settings which could be either of them though.

Also should I be using locktite or simular? Seems a bit strange that important nuts aren't lockers, especially when they are in oil..
