Use header wrap if you want your headers to rust... The heating and cooling will cause moisture to form under the wrap, plus header wrap has been known to promote cracking in headers. Best bet is to have the headers coated with ceramic by either by Jet-Hot or M&R Coatings.

Well worth it too!!!

I was VERY pleased with Jet-Coat.
It will make them last a life time, plus guaranteed

John is 110% correct. I purchased a set of headers and made the mistake of wrapping them. Within 6 months I began to hear small leaks in the exhaust. Just out of curiosity, I starting poking around with a screw driver and immediately felt the screwdriver poke through the header wrap and header itself. By far, this was the biggest waste of time and money I have spent on my Z. Do not do it! Take the advise of others, spend a little more money and have them professionally coated. They'll look better, and you will not regret it!

Just another thought here: is it important that you can touch the header wrap without burning your hands???...how often do you do this???...do your friends insist on touching the headers on your car???...my understanding for wrapping headers is to retain the heat inside the headers (more efficient???) not to make it easier to touch them...and the above comments are RIGHT ON!!!...forget the hype.
For an all-out race car (or Ricer Wannabee) then they are fine...but... )

Yup I've told people before that wrap rusts them out-FOR RACE ONLY. I have a set sitting on the garage floor that I spent hours wrapping to perfection, but I won't have them on my car now-you could see the rust soaking into the material when you washed the engine compartment.

I used the wrap not for efficiency but to decrease under hood heat perhaps for the carbs.

I am thinking of using a blanket type insulators. Anyone experienced with that?

Zbartsky...

Spend the money and have them coated. Will lower the undhood temps. Check my above post for the addresses of coating shops. M&R will coat a inline 6 header, inside and out for $140.00.
