Anyone run plug wires underneath headers on a BBC?

[Musclecar]

I have run my wires under the headers for over a year now and have not burned a set of wires yet. When I was running them over the heads I went through 2 sets in less than a year. I am using the thundervolt wires(10mm). I have them zip tied together and some of them pulled up against the block to keep them off the headers. I used this set up on my 468 and now on my ZZ502 with no problems
