Well I'm running the MSD ignition+wires on my car gapped at .065 now, seems to run a little nicer. I have seen better gas milage though (for now) on 3 tanks already after installing it. The only downside is when it's really cold it has rough idle until it warms up.
The ford racing wires are just bigger wires, I don't know if that means you're going to get a bigger spark though. You might just be getting the benefit of having a larger wire able to carry a little more voltage.
I don't know about the Solo II rules though man, sorry can't help you out there.
