Checking the cells on my Lifepo4 pack, i noticed that some are at 3.3xV and some are at 3.2xV after being fully recharged and sitting overnight.
Is that normal? Or should they all be at some other voltage level?

Support V is for Voltage
And yes, right after being fully charged they are at ~3.7v...
Should i be worried that some sit at around 3.2 and some sit around 3.3 or is that a normal variable at rest after sitting for a day.
The Thundersky cells we have average 3.344 when fully charged, or nearly so.
when you measured 3.7v, did you measure that on all the cells?
or just some of them?
what exaclty is connected to the cells?
is there anything connected at the cell level?
is the controller always connected at the pack level?
is the charger always connected at the pack level?

As I know , it's normal . Even if some are 3.7V or 3.8V when charging , but it will be reverse to 3.3 or 3.2 as lithium battery performance .
