It is a much more straight foward way of routing them and looks cleaner from the inside however; it means that the hoses come out of the cylinder head/inlet manifold, bend round and go over the inlet manifold and exhaust manifold. This has lead to the hoses looking very untidy and clutered compared to other engine bays:

I'm in the process of cleaning and repainting the engine bay and these hoses are spoiling it.
I can route the hose coming from the inlet manifold, under the carb and the hoses coming from the head i can tuck behind the rocker cover and clip it to the inlet manifold. But i don't know if the hoses will withstand the heat. The one under the carb is only a few mm away from the exhaust manifold which obviously gets very very hot and so does the inlet manifold which the hose coming from the head will be in contact with.
So will the hoses just end up melting with the extreme heat or will they be ok?
