Longtube Headers O2 Sensors?
Ok so I've been running bosh 13111 corvette rear o2s for a while my question is this, are they a good choice because I think my car is running rich not sure if this could be a cause? also im getting some oil consumption like 1 quart every 1000 miles?

Id be worried about the quart of oil. Are you running a catch can?
Did you get it tuned after the header swap, and do you still have your cats? Headers with change your a/f ratio, and if not running carts you usually get a small fuel smell

I ordered a new computer for my 04 GTO a while back off of eBay, PCMs for Less I think....you give them your vin number and they flash a factory tune into the computer and ship it to you for around $100....then you could send that computer to Frost....or he might even sell you one

You would need datalogging software that can read the mV of the Upstream and Down Stream o2's and see if any of them have developed a "lazy" reading, meaning slower then the others.
The oil issue is 90% of the time due to the PCV system. Install a catch can if you have not and see how much you get. Once I installed headers I started to get oil in the intake, installed the can and dry ever since.

They are fine.

I think i have a cheap obd2 to laptop that I shows me the logs of the o2's what are the ratings that are considered "normal" between what and what number??

Its not so much what the number is. Its looking at the first set and vs the 2nd set and when one goes you will notice it be lazy or lag behind. The other set. I am sure a PCM guru can get really in depth with the mV readings but that was always what I looked for. If one side had a large varience or if the recovery was slower one side to the other.
