Plugs and wires for 71 440

[Skytrooper]

71 440 with headers. I am looking for correct plug wires and a better plug. I think the cheap wires are failing.
Obviously the headers make a difference in what wires I need (at least as far as the shape at the plug). Without a lot of online searching, does anyone know , or recommend a certain set of wires ?

Headers are hot and close to the wires. I like MSD wires when I have headers.

I really like firecore wires they have many race cars using them. I use them with exhaust manifolds, plain black look good to me.

For plugs:
Either Accel U-Groove (now C cut) https://www.summitracing.com/parts/acc-0416s-4/year/1971/make/dodge/model/charger
or plain old Champion Copper Plus

Wires:
Taylor, MSD or Summit

I have a Summit set on my Charger with all straights, don't look great all straight but they sure work well.

You might need spark plug heat shield boots on the wires with the headers.

I used 6 90° ceramic boots and 2 straits with my headers. The heatshield sleeves still allowed the boots to burn and miss. The Taylor ceramics cured the problem. Also had to run 2 Accel shorty header plugs.

If you’re looking for an original style wire, these are excellent. MSD are good too. Like me you likely need wire holders to keep them off the headers. Run NGK plugs if you’re making power.
