The blaster process will really only clean the exterior areas, there is a certain amount of red colour left in the inside parts of the manifolds but this will not mater .
I have never known of coating the inside of a manifold specially the exhaust as it will be burnt off , also you do not want any coating on the inlet flaking off later on and going through the engine .
Yes these latest pictures are after the blasting and coating , have a look at the start of the thread for a before picture.
