Non-solid core spark plug wires for pertronix, How do you know Options

[bbrock]

In the home stretch toward first start of my engine and hit a snag. I think I have solid core wires which is a no-no with Pertronix. I bought this set in the 1980s (probably from Tweeks) and unscrewed the connector just to check and found this.



Those are copper strands, but does that mean this is a solid core wire? The coil wire is labeled "suppressor cable" and looks to be carbon, but the plug wires are not labeled as such.

If I need to buy another set of wires, how do I know what I am getting? Karlyn/STI makes a wire set with all short connectors that would be preferred for my carb setup, but their description is vague:

Product Features

- Unique Tinned Copper Core
- Greatly Exceeds O E and Competitor Specifications
- Double Extruded Silicon-Over-Silicone Wire
- Contains 19 Strands Of Tinned Copper Core
- Super Conductivity w/Superior Corrosion Resistance
- Limited Lifetime Warranty

What wires are people running with their Pertronix Ignitor II or III? Apparently the Ignitor I isn't as sensitive to RFI/EMI as later models.
