header wraps

is it worth it to wrap the headers or is it not really that much more effective. i already have a crossover wrap and that reduces a lot of heat from hitting the intake. i look under the hood and contemplate if spending that much time trying to wrap each header will noticebly improve running conditions, and then the hood falls, hits me in the head and i forget what i was doing.

surprised the headers arent already coated. Anyway, I don't really know, If it is getting hot under the hood then maybe you should do it. But I heard header wrap also makes the headers rust out faster.

Well, Zoomer, over at ZZPerformance, appears to have done a fairly thorough study on the question of exhaust coatings (http://www.zzperformance.com/zzp/info/engine_exhaust_coating.htm).

He seems to really know his stuff, and it appears that his testing methodology is pretty solid. You may want to check it out.
