I've never coated a set of headers with heat boxes to be honest. Every Porsche header set I've built has been sans heat. You cannot physically coat the inside of the heater boxes without taking them apart and re-welding after. You can coat over them on the outside with the rest of the header, as well as inside the primaries.

I'd imagine you'd get some heat loss, but you'd still get heat. The coating doesn't cut heat so drastically that you still don't get hot headers.
