I can only tell you about mild steel headers:  If you wrap them they will
deteriorate at a much faster pace.  If you ceramic coat them (and that is
done to both the inside and outside) it will increase performance as the
exhaust gasses will flow faster and it will also lower your under bonnet
temps and keep your carbs cooler.  But, .. there's more...... ceramic
coating them will preserve them for many , many years. They will not burn
up as all un-coated headers will eventually do.

It's a good idea. My BN7 has become almost impossible. To drive in the summ=
er except at speed on highways. Vapor lock is a huge problem although my fu=
el lines are not all that close to the manifold, coming into the front of t=
he SU's via a regulator.
I have a shield I hope to put on soon to help. Fall winter and spring days =
are no issue.

Heat and this ethanol fuel is a definite problem with my BN1 and I'm sure t=
he same happens with BN2's also and from what Keith is saying, it seems to =
also affect six cylinder folks as well. From what I heard, a lower boiling =
point for the fuel has a lot to do with why the "vapor lock" symptoms occur=
.
This is how I solved my problem with that happening while stuck in traffic,=
 starting up after sitting for a short time after a hot run, etc.

This is a marine bilge fan I got off ebay, painted flat black and wired in =
next to my radiator for easy removal and no holes drilled. 3" flex off both=
 sides, front goes to right behind grille and sucks cold air in. Rear goes =
right to front float bowl.

Better view of install. Simple. My car is a driver and I had a terrible tim=
e with these new fuels, so the sight of the install doesn't bother me as it=
 solved all those problems.

The 3" flex is bent and pulled right to the float bowl. If I sit, I turn th=
e fan on from a switch inside the cockpit and let it run for about 30 secon=
ds before firing up and now problem. When stuck in traffic, flick the switc=
h and instant cold air stops vapor lock. When going down the road, flip the=

May be you should check the pressure delivered to the carbs. The 
pressure regulator may be set to low, hence vapour lock. You can also 
run a return fuel pipe/hose from the carbs to the fuel tank 
incorporating a restrictor to keep fuel in circulation and thus cool.

                what about paint?  I have a set of mild steel headers

                really want to leave them bare, and I was planning on
                painting them with high-temp paint.

                  behavior for these cars although I've always wondered
                  about wrapping the the exhaust manifold to decrease

I'll crank it up a bit. Not sure yet of the PSI at the moment with the elec=
