Spark Plug Wire Separators - Conductive?

[69Nova396SS]

Is it ok to use aluminum spark plug wire separators? Are they too conductive?

the set you are looking at doesnt have plastic pieces that clip onto the metal like the set in the link?

No, I was thinking in terms of the ones linked below:

Since there is no rubber or plastic between the wire (other than the wire insulation) I am wondering if they would be susceptible to spark jump?

If you have a good set of new wires it shouldn't be an issue but read the notes on both of them.
