I'm about to pull the trigger on some FPA's for my `57 bird, but I hope it's ok if curve this topic abit... toward ceramic coating.
If aesthetics or radiant heat werent a concern, wouldnt it be sufficient, if not preferred, to ceramic coat ONLY the insides of the headers?
Also, have done a search of the archives but find no discussion on HEADER WRAP. I personally like the look of it properly applied, but have seen extensive debate on it's deteriorative affect on the headers themselves... though I think the problems have to do with the wrap applied with adhesive rather than the stuff like Thermo-Tec that is water soaked before application so it conforms and "shrinks".
Coat the inside and wrap the outer?
Cheers... Brian
