No help on where to mount them, but even if you don't have the dual headlight mod, you'll be really close to drawing too much wattage from the bike. I'd recommend looking into some LED driving lights instead.
Edit-
I read that the total wattage available is 182 watts. Here's a breakdown of all the lights on the bike, this isnt counting the watts the computer/FI system pulls. The bold ones are always on.
