ok this is something i haven't ever seen and maybe its ok but i just pulled up in the car and popped the hood and its dark outside and the headers were glowing dull red on the 2 inside tubes on both sides....tell me this is normal!!
How long had you been driving? What is the wall thickness of your pipes? Were you running at high RPM? If you were only going a short distance at low-mid RPM it would indicate excess fuel, get it checked with a gas anylizer. No it's not normal with quality headers.
According to my IR temp guage the two inside cylinders are reading 550 to 575, so yes at nite IM sure they would glow. Still have to fire her up at nite to see. Pretty sure its normal. Didnt want to fire her up in summer darkness, but its something I want to see soon.
ok the headers are brand new, dynomax ceramic coat. but yes i was running high rpm. the carb is running rich though..need to get the fixed.
it wasn't a bright glow..but bright enough to see..it was a big shock because i had never seen that and panic was running through my mind because at first i saw it on the driver side..which still makes a small tick noise after i just got done putting the new heads on and adjusting the valvetrain. so i thought maybe it was related. but then i went to the other side and it was glowing the same...i guess it only was glowing on the inner tubes because there right next to each other and the heat just transfers accross the 2. on the side..this tick i have isn't loud. but i noticed the dynomax headers practically touch the steering box.. so i need to dent it in, there is like a hair clearance..perhaps when the motor is on it shakes and hits the steering box but i have solid motor mounts...
I have the same headers and I know what you mean by the driver's side tube hitting the steering box. Mine basically touches. I have always been worried that it is transfering heat to the steering box and causing some kind of damage. I have never seen mine glow, however I can't remember the last time I looked when it was dark
I also wonder if it can eventually wear a hole in the tube over time. Probably....is bending it the only option? Anyone know of a different pair of headers for a 327 that don't touch the steering box?
This happened to me once many,many years ago.It turned out to be a timing problem-retarded(like me at the time).Once a friend straightened my sorry butt out on how to really set the timing,no more glow-in-the-dark tubes.
Sounds to me like you have a vacume leek. Have you had the intake off recently? I have only seen the headers on a car glow red twice in my life and both times i resealed the intake and that cured it.
I hope this helps,

usually indicates a timing problem but the rich condition will also contribute what is you timing running at? check it out . I wraped my steering box with a thermal blanket the kind you get for a starter I think it helps
