Header wrap

Agreed with above posts. Do NOT wrap them. not worth the aggravation. I had a buddy do his and they smoked horribly, and they backed up the heat into the heads....the header flanges would literally glow red because the heat that was radiating...was now confined by the wrap. if you have cooling issues, or underhood temp issues. You need to be looking into an electric fan, better radiator, A/F ratio....anything but wrap.
