I've always questioned the use of header wrap. Personally I think the ONLY purpose it serves is to give YOU some protection if you happen to touch bare skin to a hot header. Not to say you won't get burned, just that you won't stick the the hot pipe!
As far as reducing heat in an engine compartment, I don't think so. Sure, the wrap keeps heat in the pipe but only until that heat transfers to the wrap, then it dispells or radiates the heat just like a hot pipe.
And as stated in the previous post, the heat will weaken the headers and decrease their lifespan SIGNIFICANTLY.
Great for racecars but has no place on a street driven vehicle.
As for tying it off, I've always used safety wire. I use a nylon tiewrap to hold the end, cut a long piece of safety wire, loop it around the pipe then twist it about 3/4" then wrap it back around and twist it tight. Leave about a 1/2" and trim off the excess. Flatten the twisted end to the header. Cut the nylon tie and pull it out.
