Do long tubes help the engine cool down faster?

Usually gets hotter.
I had my headers coated despite being stainless steel. Underhood temps are significantly lower than a friend of mine who had uncoated headers. He actually got his coated since it was pretty unbearable to open the hood, felt like opening an oven. It's pretty deceptive in y engine bay, while my headers get cool enough to maneuver around, things like header bolts, coils, air tubes etc still hold a lot of heat. I was getting mini 3rd degree burns today trying to change wires due to touching the various things around the headers after 30 mins of driving the car.

It will come down to heat dissapation properties of all of the metals that are connected to the engine and how will the engine bay can allow the heat to escape out. Large and heavy (ie. Iron) objects tend to hold heat in longer as compared to lighter (ie Aluminum or thin tubing) and smaller objects.
The thinner metal of a Header (and if coated header) would most likely cool down faster than a stock cast metal exhaust manifold. But I don't think it will assist that much in cooling down the rest of the engine itself as a whole. So in a very, very small way, yes it will assist in cooling down your engine faster.

I guess I can kinda see the point of this question...FWIW, my headers cool down much faster than anything else around the engine. The heads, transmission, spark plugs, etc remain hot for a long, long time compared to the headers which are cool to the touch after about 20-30 minutes.
