header question

RE: header question
It's running lean and way too hot. I once forgot to put the main vacuum line back onto the upper intake and I let it idle for about 20 minutes when I realized my headers and cats were glowing red. Didn't hurt anything except the cats which rattled after that, still passed emissions fine though.

RE: header question
what changes did you do prior to this happening???? valve events is more than likely the culprit.. change the dizzy? cam? timing chain? sounds like valve timing off a few degrees.. not just the advance... actually valve events.. if its on jacks you been doing something... we need a bit more info to try to help better
