Are all the spark plugs oil fouled or just 1 or 2 cyls? If all fouled I would suspect a faulty breather system or baffle assy in valve cover.

Try running with all breather lines disconnected & see if smoking gets better/worse

I tried to use cheaper parts, caused me grief. I try to use good quality or OEM parts when it comes to engine overhaul. How many hours on the engine??? Did you flush and test rad,water pump, thermostat ect.. ?? 4g33 or 4g63
