I honestly doubt you'll find, feel, notice, etc any difference using non-stock wires on a motor essentially stock...

Hell I've read reports where "LARGE" diameter wires negated performance. I forget exactly why, something about the electricity having a larger range of motion before it actually hit the fuel

The only real benefit that I can see plug wires having; apart from using utterly cheap wires, is using wires with a larger diameter just for the extra heat protectoin. My lt1 with headers used to burnt wires horribly if they came anywhere near the headers. That required better wires, simply for the heat control.
