Engine bay questions

Not sure this is the correct forum page for this...

In my 71 swinger w/ 318 I am replacing the plug wires and want to re-route my heater hoses. Just going to run accel 8mm wires, and more curious how you guys are routing your wires mainly on the driver side to clear the taller exhaust manifold. And then also as you can see in the pics my heater hoses just rest on the valve cover. I’ve seen on some B bodies these other brackets(pics of the yellow car) are those brackets on the fender well and alternator something that would be on an A body? What are they called and where could a guy get them? And mine is a factory ac car but all the ac is removed. Do I really need that valve in line of my heater hose or can I pull it out and save it for later if I put ac back on?Any pics of your routing are appreciated thanks.
