Looking for the pros input (Trev?) on this one. I have always run the headers on my 911's uncovered, no blankets, no Inconel, just exposed. My 911's were all air cooled (and tracked) and of course had the propensity to run hotter than a water cooled engine but always run just as cool (or hot, however you want to look at it) with the uncovered headers. So with the rather open air, relatively roomy engine bay of the 360 would it not be a good idea to allow the headers to be cooled via the surrounding passing air? Does the blanketing or Inconel hold the heat from cooking up the engine compartment at the expense of engine and header cooling? What do the experts here think?
