mopar performance plug wires

i was just thinking the mopar performance 8mm wires would be cool because they would match my mopar performance valve covers. I decided on getting a crane cams hi-6 cd ignition so i know what i'm going to run with ignition and the crane box is going to be firing alot more juice thru the plug wires to the plugs so i figured the lowest ohm per foot of resistance i could find in a wire would be the best for the hottest spark possible.
How far will i be able to open up my spark plug gap once i install the crane hi-6 ignition box? i'm running them at .035 gap right now i was thinking i could at least open it up to .045.
As far as wires i'm looking at the mopar performance 8mm wires and the taylor thundervolt 8.2mm wires and the crane cams fire wire wich is an 8.5mm wire. The mopar wires would be the chepiest then the crane wires and then the taylors being the most expensive. I will be running the crane cams hi-6 cd ignition and the crane cams lx91 e style coil.
