Your Lang, like mine, is a reverse flow, and doesn't need tuning plates. For those that have the traditional setup, with a firebox that dumps heat directly into the smoke chamber, tuning plates help shrink or eliminate the hotspot by the firebox. They really make a difference in the smaller offsets.
