      why do headers glow???

      Well first off the motor is a n/a ZZ430, air gap, holley 750 nothing special. I just changed my intake gasket (was leaking) and just installed the brand new headers which HEDMAN was so kind to warranty for me due to a crack in the pipe. But yesterday I drove the car for the first time in 6 months and while I was on the freeway my friend who was driving next to me called me and said my headers were glowing?? uuummmm??? well timing is set @34* @3,700rpm not sure what else you would need to know to better help me. Could this be a possible lean condition or timing issue? Other than that the car runs fine no sign of anything being out of whak.
