That`s the thing about it, they had no color change period, like new out of the box.
Good, brand new plugs on unleaded fuel should look clean white with a small gray fuel ring at the very bottom of the porcelain.

If the exhaust starts to glow orange, then the timing's too far retarded advance it a bit...
Relax dude, just building a consensus, I want to try 1 thing at a time to see if 1 thing would be a cure. That would be highly informative,to me, and to the next guy who might experience the same issue. Plus save me on gasket/s. I appreciate all who try and help, I`m not ignoring anybody. This time around I`m not going to panic, if I detect the slightest glow, I`m shutting it down and installing the jets. Unless these site builders reply and say NO-NO-NO-JET IT FIRST, I`ll jet it first.He only been old this around 10 times now.

Exactly Right!Glowing headers is an indication of retarded timing first. With the timing being late, the fuel is still burning leaving the cylinders, because the ignition is started too late so it continues to burn. This reacts the same as a lean mixture, since all of the fuel is not burned inside the chamber. Bump the initial timing up.
Couldn't be more wrong!The only thing increasing the timing might do to your jetting is make it LEANER, and you have been told to go up on your primary jets irregardless of what you do with your timing, but do what you want.
100% ABSOLUTELY RIGHT!I was trying to s
I was trying to stay out of this, too many bad suggestions on where to start. I own/run a dyno, we have thermo couples in the headers we run on the dyno. During engine break in if the exhaust gas temperatures are getting to high, the first thing we do is advance the timing. It is pretty common for us to use 36 degrees total advance at 2,500 rpm. If you make it richer without advancing the timing I believe you will burn even more fuel in the headers and they will continue to glow.
