On my 305 V6 with a 4 barrel, I stayed with stock type NGK plugs and stock type wires and installed a pertronix. Hardly if Ever pops on deacceleration now.
On my 292 with a 600 cfm edelbrock I installed an HEI, Napa 8 mill wires and 1 step hotter on the plugs.
The 305 V6 has been burning the fuel without issue so I haven't seen the need for bigger wires or hotter plugs.
