There has been a bit of discussion regarding the intense heat from the "Kooks" header actually melting the plastic (sylicone) wrap on the cables. I found a Speed shop that Caters to a lot of the NASCAR teams, and asked them what the best item is to use, to block the heat, and keep the cable covers from melting.
They gave me the same stuff that the Race teams are using to shield their lines. It was 1" diameter, so I slipped it over the cables, and then folded back over and secured it with aluminum tape.
Here are some pictures, if anyone is interested.
