Get the header uncoated. Don't bother with their coating. Don't bother with header wrap.

Send the header to Swain Tech.

Most ceramic coatings are little more than high temp paint. The Swain Tech coating is a thick coating that is a true thermal barrier. It's far more effective than the usual header coatings. It comes in white, but believe it or not it's paintable. It's a rough coating as well. If you want pretty, get another one.

My Infiniti G20 had a header with a conventional coating when it was NA. When I installed a turbo engine I had the exhaust manifold, turbine housing, and J-pipe all coated with Swain's White Lightning. The under hood temps with the turbo engine were noticeably lower with the turbo engine with coatins than NA with the conventionally coated header.

Swain has a client that uses underground locomotives. They had to lower the external temp of the exhaust manifolds from 925*F to 425*F. The conventional coaters could only get to around 725*F. They then called Swain. First try they got 475*F. With a little thicker application they hit 425*F.

You'll pay a little more for the Swain coating (but it doesn't sound like that much more), but it's the most effective you'll find.
