Jeff,
Jet hot has several formulas now. If trying it be sure to get the highest temp version. Not saying it will work for sure, only that it is the best coating option. Best durability and lightest weight is a custom inconel manifold and a radiation shield.

Hey Bobby, that RANs S21 looks like a nice airplane ... another high-wing (not too many) coming to the Rotary world ...  the rotary should give that decent performance.

I used Jet Hot on my first custom manifold. It flaked off within a short period of time. The "professionally" build 321 manifold burned out at the rectangular to round flange transitions. Due to the ceramic coating I decided not to try and weld in a repair. I've decided to not to have any new manifolds treated so they can be repaired if needed. But I could see a benefit for pipes downstream of the manifold.
