best 02 sensors
With headers, any brand O2 sensor is a crap shoot. FWIW, I've had GM O2s that lasted for about a year before they got too lazy, and it was the same with the Bosch 13111 sensors.
Right now, I don't even have O2 sensors, and don't plan on ever putting them back in.

It seems with long tubes, atleast with my car, both the stock delco and the bosch sensors will eventually start throwing codes after 10k - 20k. However the bosch are considerably cheaper and they perform very well, even when they do throw codes (and you disable the DTC with a tuner).
After going through 14 oxygen sensors in the life of my car, id rate the bosch as the best buy because of the extended wire, the heater, and the switching activity all for a decent price. The stockers are good also, but theyre more expensive and require extentions. The densos, however, I rate as **** poor.

The symptoms you typically see with a long tube eader car is that the o2 sensors start to fluctuate (switch) less frequently. This usually trips the insufficient switching code and sets the SES light. Many things can cause the o2s to fluctuate slowly, such as too low exhaust temps, fouled and caked carbon deposits, lead and silicon poisining. Even if you eliminate all those possible issues, the sensors still tend to go bad with time and miles. You can pull the sensors out and clean them by hitting them with a propane torch for a few minutes to burn off all the carbon deposits, however usually after a few days the codes come back.
O2 sensors need heat to work...LT headers have a great deal more surface area, and the exhaust gases cool a good amount before it gets to the sensors. Although our sensors are heated, they can't work miracles...
