Ring seating?

Ok I just rebuilt a 370 using wiseco pistons and their rings. .021 top gap and .023 second ring gap for nitrous later on. After initial startup and getting to temp I changed the oil. Truck was open headers so I couldn't drive it a lot but did a couple short pulls down the dead end road up to 4500 rpm. Truck has a little less than probably 250 miles has used almost a quart of oil. Did I not seat the rings properly or could they still be seating? After I put the mufflers on I did get up to speed and engine brake it a few times. A little blue smoke is coming out of my filter on the valve cover that I have. Thanks for the help

Did you data log the runs?
Where in the headers do you have the O2's?

Could the oil loss just be from the pcv and filter on my valve cover? Pcv goes to back of carb and i have a small breathet on my passenger valve cover

Just drive the truck tonight and I couldn't see any smoke coming out if the valve cover breather. I also took the oil cap off while running and it had a light suction. The truck pulls like a freight train and the motor feels really healthy.
