master cylinder vs exhaust heat

[upon1]

Im in the process of doing the exhaust on the '55 but not sure how I should be routing the drivers side off of the manifold. I have installed the master cylinder and there is room to run it straight back under the booster when it is aired out but am a little worried about heat. I will be wraping it with header wrap as well. I could also angle it toward the outside of the frame and back in after the master cylinder. What have you guys done? Here is a pic of the setup.
