This an assembly specifically designed to spread out heat, applying heat to the pipes will just make the whole thing hot. If you did take a giant blowtorch to it and got it hot enough to soften the pipes, you’d probably dry out the pipes (potentially explosively).
Heat pipes are cold worked in the factory. The metals chosen are ductile. Adding lots of heat will only add to the problems.
