no noticeable leaks, will check more thoroughly today. believe it is due to not being hot enough. cold o2 sensor = low voltage, correct ? i see you're wide open in the exhaust, you've never seen this code ? will run efi log for first time today maybe that will shed some light on it.

Maybe try switching the sensors left to right and see if the code moves to the other side.

What kind of headers are they? Are they coated to keep the heat in? I would think that with the heater in the o2 they would stay hot enough though.
Seems like theres alot of guys that get these codes after a header install.I've never seen a solution though.

What kind of headers do you have? I had that problem with my TOG's before they were coated. It's one of those things you will just have to live with or turn the code off with EDIT. If it's the same thing as I was getting, you are running a bit rich too.

they are edelbrock shorties, ceramic coated in and out. got ses with s.c before headers but it would always clear itself, now it stays lit. maybe since the headers at higher boost/airflow the whipple injectors aren't compensating enough, causing a lean condition. i'm going out to log with efi live now, see what i come up with. didn't think of that before because the whipple dummy [lean] light has never lit other than during the start up self check. thanks for responding guys i'll give more info when i decipher the efi log.
