I haven't bought plug wires in a long time, and I'd like to replace the (now dirty

) red wires that the Ram Jet crate engine came with with black instead. Any recommendations? Heli-Core? Accel?
I initially thought about running them under the headers, but with the big tube headers there's really not a lot of room under there and the stock loom that the engine comes with does a good job of keeping the wires away from the hot tubes.
Thanks,
