The smoke could be coming from oil dripping down onto the exaust manifold and burning off. It is important to make sure your new valve cover gasket is not leaking oil. If it is not leaking, it is possible that some oil dripped down during the installation. Keep monitor of your oil level. It may take a while for the oil to burn off.
Try changing the valve cover gasket.
No, it will not cause smoke from the exhaust pipe. However the leaking oil can drip on the exhaust manifold where it will be burnt and smoke.
Valve cover gasket.
Oil leak? Valve cover gasket? Power steering pump?
Not directly, but it can crack or blow your head gasket. (Which will cause white smoke) Happened to me =(

leaking head gasket
The carburetor needs calibration or changing of possibly defective part, for example, gasket or needles.
sounds like it might be head gasket or intake gasket
Most probably, you have a valve cover gasket that is bad, and the oil is dripping down onto the exhaust manifold, and is being burned. Replace the valve cover gasket.
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
Head gasket or cracked head
