M18/25 exhaust manifold questions

[mherrcat]

Anyone know what the torque requirement is for the nuts on the manifold studs?

When installing the manifold studs, is there a torque requirement for those as well?

The manifold gaskets are metal, so I assume there is no sealant required on those?

What about sealant on the exhaust flange gasket to the exhaust riser? This gasket is some kind of fiber gasket.

No sealant is needed where there are gaskets.
I don’t know torques specific to your model engine. However, the service manual for the Universal 5432 and others in its family includes the two pages I have attached. They may be of some help for you. I am not a mechanic. Perhaps others in this forum have better information for you.
