 I take it I have to use proper heatproof paint for this as painting it silver

 

only have some silver paint but not realy heatproof as such

[Carlos W]

It gets very hot. Normal paint will just burn off

I found that even heat proof paint will flake off if its been lying around in a tin a few years, i used half a tin on my 998(2009), then used the other half earlier this year on the same engine, it was so thick even after attempting to thin it out, it went dull lol

You did say inlet manifold... not exhaust?  Paint the inlet with any quality paint you want.  The paint is more likely to be damaged by splashed gasoline and oil than by heat.  Yes, inlet manifolds get hot due to proximity to the exhaust manifold... but NOT that hot.  They are cooled by the incoming air and some are connected to the engine's cooling system.  Figure on the intake manifold getting no hotter than an overheating engine... say 250 ^oF or 120 ^oC.

 

The exhaust manifold is the one that needs something a little different.  You can buy high-temp exhaust manifold/header paint.  However, if you don't mind "black", use Barbecue Paint.  It has higher solids and binder content than the automotive paint and will stay in place and look nicer longer.

Perhaps I should read properly before commenting
