Exhaust manifolds, gasket or no?

Looking for opinions on whether to buy exhaust manifold gaskets or intall without. I know my old gm diesel had you put a coat of grease on the flanges and torque em down.

No gaskets unless they are warped and then I would have them machined flat

To my knowledge, there aren't any gaskets even made for the 7.3. By design, it's a gasket-less setup, as per International.

Both IH and Ford have gaskets, as well as Fel-Pro's(aftermarket). From the factory its machined. I've heard many guys having great luck throwing on a set of gaskets when they have manifold leaks. I also believe multiple shops add gaskets when they have the manifolds off. I'll be adding gaskets when i pull my manifold off, and depending on how they look and what it costs, i'll be having them re-surfaced as well.
