This is opposed to a motor that would be able to make a full revolution with the valve at max lift, without the piston hitting the valve.
When I lost the timing belt on the Neon all 16 of my valves were bent. If you want a souvenir I've got plenty.
New valves
The top end should be good for another 100K miles now.
