That's a crazy picture.it looks like the valves are all parallel to the head face.

We only had to replace maybe 1/3 of the valves. I guess what matters is what type of chain failure happens.

In one case the chain broke and froze all the cams so only whatever valves were too far in at that point would be a problem and the engine killed so wouldn't keep spinning to cause more damage.
