Header & Wiring

I just put some Dynomax coated shortiie style headers on my 305 and need to redue the ignition wiring. Any suggestions on wire looms or any good method of running the ignition wires?
By the way, I recommend the Dynomax headers, they not only look good but they have a nice tone. My ride is a '82 Camino SS and the header I used is #86118. One suggestion is to put a slot in the back flange bolt hole so that you can place the bolt in and then slip the header on the bolt, then install the rest of the bolts.
Having the A/C box on the passenger side makes starting that last bolt a bear.

Never thought about running the wires from underneath. Sounds like a good idea. I did try removing the wheel but the inner wheel well still limits the access to that last bolt. Thanks for the input.
