Manifold nut torque

[anothere21323i]

I've got a new set of exhaust manifold gaskets/heatshields for my 325i Touring which I'll fitting this weekend along with a new manifold/downpipe gasket. I've also gone for a new set of manifold studs and bolts which I'll do at the smae time - there is one borken stud so it's as well to do it all in one go.

My question is this - does anybody know what the correct torque to tighten the copper nuts is?

Also, should I be using any sealant on the gaskets, or just assemble them dry?

Thanks in advance!
