Valve lifters and rocker arms are almost the same, the work next to each other with the lifters pushing the rocker arms.
From the description of the symptoms, it does not look like it is caused by the lifters or rockers arms.
If you have black smoke, something is burning and it could be the wire harness. Oil would not burn with black smoke unless there is a big fire and if it is coolant leakages, steam would be the result.
It is not easy to access what is the cause or resultant product without understanding what had caused the engine to stall.
If it is rocker arms which had failed, to drive further would not cause much problem but still not advisable to drive because if 1 cylinder is misfiring badly, it would cause damaged to the catalytic coverter resulting in it heating up red hot after some driving.
Since the vehicle is not starting now, you should try to isolate the source.
1. Ignition or electrical fault. Check for sparks at plugs.
2. Fuel. Test for fuel pressure at fuel rails.
3. Check if the timing belt is still intact and working.
