The valve noise on that engine is terrible … if the uTube sound is believable. That means the valves are not opening to their proper distance, maybe not at all. Maybe one or more are stuck open a bit.
At this point I would let the engine run at dead idle for a long time. If the lifters do not 'pump-up' in an hour or so, then it is time to do a valve rocker adjustment. If it is still back firing it is time for a compression check. A slightly stuck open valve will show up in very low or maybe even zero cylinder pressure.
