    Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

    A costly lesson learned today. With an ECU controlled timing system, setting base timing is a two man job, one to work the timing light and make distributor adjustments; and another to work the calibration module for Base Timing Mode ON/OFF and to adjust throttle position to the required rpm. Doing it alone results in cooking the pretty ceramic coating off of headers in about 30 seconds because leaving the system is Base Time Mode for anything more than a few seconds pushes tons of raw fuel into the headers. Jet Hot will be getting a set for a second round of coating $$$, unless I paint them black......

    black barbecue paint till you get some miles on it is how i would go . all the header builds i did i would paint them with barbecue paint. so there was some rust hold out till they got them coated .it is very thin.. you have to put many thin coats on .but hold out is not bad still have that stuff on the chevy headers still look good over ten years and cheap

    What's frustrating is that I knew the base timing was right, but to eliminate doubt expressed by my tuner I checked it once more and toasted the headers. $300 gone in about 20 seconds. I'm not a happy camper.
