These are the back plugs so you have to remove the manifold to get to them... not a simple task.

Where was the oil? Was it on the spark side inside of the cylinder or outside suggesting an oil leak somewhere else.
If it is in the cylinder it's probably the rings. Is it missing/Running Rough?
This is a plug out of a non-firing cylinder out of one of my irrigation motors. You can see it crammed oil into the gap of the plug.
This is bad. This needs an overhaul. Sell the car before you get this. Chevy 350s aren't too expensive to overhaul. This would get ugly.
