Intake Exhaust manifold

[DG123GT]

Need a bit of advice.
Having taken my cylinder head and twin carbs off for a refurb I was wondering what people thought about painting the intake/ exhaust manifold? Looking at mine the intake seems to have been painted silver at some point and I have been told that the exhaust manifold should be painted black. Is this what others have done or should the whole manifold be black? Also should I paint the heat shield black as well?
A bit like this chap. Although his intake is aluminium you get the idea.

Did mine black. Exactly the same as in the picture. Well worth doing and a simple job. Seem to remember getting the heat shield black powder coated.

Never tried it myself but appears to do the job.

I've heard that a ceramic coating is better. The temps might be too high for powder coat asnd it could melt and drip off.

I have heard, so may be false, that ceramic coating on some older vehicles can actually cause damage.

Reason being, that as the manifold will be hotter, due to not dissipating the heat externally, it can in turn heat the surface of the block if under load, potentially causing damage.

However I have found nothing to support this!

I don't think there is any issue with overheating of the engine block due to fitting ceramic coated exhaust manifold.
Have driven more than 6,000 miles since fitting and a considerable amount of this has been at prolonged high speed over the last 18 months.

I wouldn't worry about it ,
it's probably getting no hotter than using exhaust wrap which the drag racing guys use to prevent the engine bay getting to hot and causing fuel evaporation,

and not to mention that the exhaust travels through the head before it gets to the manifold.

Hi Ya

Im going to say three letters then call it paint afterwards nice and simple

V.H.T Paint have done it for years now no worries at all no damage and comes in all great shades of colors

Extreme heats not a problem at all as proven by many other folk using the products all over from exhausts to flus inside the house coming outta the ranges etc ...............

thats what i do when overhauling secondhand parts to be reused on any projects ..

kind regards
