During tuning new engines lean or rich fuel/air mixtures can cause hot spots in excess of 1300F, this is one reason if you are not careful you can damage headers ( coated). Also ignition timing is very critical to exhaust temperatures which are not reflected by the water temp gauge ex 190f on gauge 1300f internal exhaust and higher, during this period use a large floor fan to cool entire engine and headers this is what Jet hot coating recommends, I did it and had no problem!!!!! 541hp LS-6 ----- Original Message ----- From: "Trooper" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Sunday, August 17, 2003 6:08 PM Subject: Re: [Chevelle-list] Need a set of BB headers
