What would cause.... red hot headers??
I noticed after running lightly for a couple minutes that my Kooks were starting to look red. I wasn't sure if this was normal...so I turned the car off.
Car is running quite rich....could that cause it?

The odd part is...seems to be acting like it is running rich.
When it idles I swear I am going to start crying.
Backfires at idle....not terrible, just a little popping. Tune is obviously off.
When driving...it hesitates badly under 3500. Over that is acts fine. But a local shop but a base tune on it for now.
When it hesitates...it has shot some fire out the rear.
Obviously not driving it much right now. I had just cleaned the MAF, replaced the O2's and wanted to see if it helped.

I had read that the Morels with stock rockers were a 22 ft/pound install.
What about too much spark advance down low? What is too much as well?

I did not measure preload. I had read to install the rockers to 22 ft/pounds with the Morel lifters and they would be fine.
I do believe I may have found the problem though. Vacuum leak. Gonna fix it tomorrow.
I made a stupid mistake and forgot to replace the LS1 valley cover bolts with the ones provided from FAST. Hopefully the intake isn't cracked.....
