Phil,
This is useful information! The exhaust manifold of my +4 has a porcelain
coating on it but this coating is chipped and I've been looking for a way to
get it fixed. I don't know if mine is coated on the inside, but a smooth
inside of an exhaust manifold should help getting the exhaust gases out in a
hurry. Porcelain is an insulator, though, and would not "help the heat
flow" but keep it from getting where you don't want it. Having said that, I
would expect that the heat would simply be radiated somewhere else and that
the exhaust pipe/muffler/tail pipe would get hotter. The heat has got to go
somewhere!
