Valves will clatter if the engine is overheating.Valves will clatter if the engine is overheating.
When your valves do not have clearance, a number of things may happen. Your valves will not be closing all the way, you can lose horsepower/compression, poor fuel economy, backfires, hesitation, stumble when idle or take off, it will make your engine run like crap! When you lose clearance on the valves, the engine almost acts like it is out of timing. When the valves have excessive clearance, they will be noisy.
It is exactly what it says. The number of valves the engine has per cylinder. If you have 16 valves on an 8 cylinder engine, you have 2 valves per cylinder.

Valves per cylinder makes one's engine more powerful or less powerful. A engine that has 2 valves per cylinder is better that a engine that has only one.
