1989 7.4 stalled while driving

What is your question?

all cylinders lost compression. replaced worn-out timing chain and gears. still 0 compression in all cylinders. whats the likliness of all the valves getting bent and staying open. seems there should be some compression in any givin cylinder even if the timing was off. the crank gear is set at 12 o clock the cam gear at 6 o clock..... baffled
