It is usually the manifold that is not flat, especially tubular types which pull when brazed together.
It took me over an hour to set up a Ulster manifold to take a cut to clean the face. Cast iron ones are somewhat easier.
When everything is checked for flatness I bolt everything up without a gasket, if it rejects a 0.0015" feeler all round then I'm happy.
