engine smoking

If my 383 engine is smoking on acceleration and deceleration, does that mean the piston rings are shot or is it still a possibility that the valve seals are shot pretty bad? I've always heard if it smokes on acceleration its the rings and on deceleration its the valve seals. Then again is that a true fact? Compression test was done a that was fine but was thinking the oil rings are shot..
