Header Coating Discolor (BG carb adjustment?)
The coating on my header's are starting to discolor. They and the Dynomax ceramic coated headers.
Does this mean that the car is running too lean or too rich?
Anyone else having this problem with their Dynomax header's?

There were some posts a few weeks back saying that high exhaust temps can be caused by too lean or too rich, that the best way to tell is to look at your plugs or have the a/f read like at a dyno.

I have a Barry Grant 575 Speed Demon with mechanical secondaries.
If it is running lean what is the best way to adjust it so it will run richer?
It has been rejetted with 72 and 65 jet sizes.
