Braided turbo lines heat wrap?

[OpHaScHiLlM]

Here is how they are installed





The oil line that goes under the exhaust manifold is touching it from below and even runs under where the manifold is bolted on to the engine, underneath the gasket.
Question - Should I take everything off and heat wrap the lines, specifically the oil line so there is no chance of it melting or is it generally not a problem?
I found two people who had heat wrapped their lines, obviously after i installed mine, one had wrapped it w/ exhaust bandage and exhaust tape on top. Any suggestions?
