Is there any temporarily white smoke after piston rings change?

After hundreds of miles running with horrible white smoke :
I recently changed :
Piston rings, Valve stem seals, head & Oil pan gaskets, head cover gasket, TB, Water pump, got the Valves lapped.
Currently it's on break-in period (Run about 80 Miles till now) when cold there's no smoke, after warm up to normal operating temperature a slightly smoking happens from time to time when rev up up to 2500.
Heard somewhere that may be the oil condensed by the old rings smoke issue is getting burned. Please if there's anyway to check and confirm this i'll too much appreciated to hear from you!
Also, what's the right way to perform a perfect break-in?

Thank you.
