I have been running rich off and on. ill get a rich o2 code flash and after about 40 miles it will go away. Which do you think it could be? Too rich or valve stem seals? Or possibly both?

Check the tune, it could be stem seals though. I would start with making sure the AFR is on.

Wideband oxygen sensor, like on a dyno.

I would keep an eye on your number 5 cylinder. It's a bit over 9% short of your best cylinder. Just make sure that one doesn't drop anymore for sure. They say a tolerance of 10% is the most you really should have in a real healthy motor.
