I'd make sure the header fits snug (when it is relaxed) put the gasket in place, then tighten the nuts, moving from one to the other, a little at a time, until they are "manifold nuts tight" ...... or your favorite torque specification.
Heck, back in the day, we used to "make" (cut our own) manifold gaskets out of a sheet of asbestos. Be damned the dust ...... we were bullet proof .... actually we didn't know .....
