Headers

It's a pain to disconnect the P/S hose so I would ziptie the heat wrap around the hose & secure it away from the headers. The O2 spacers for the post cat O2 sensors work pretty well so I would try them also

You definitely want to shield the PS line. However, rather than disconnect it, I would either wrap it with the material that you have, or get some thermal flex tubing, and use some metal zip ties to secure the material in place .
