2014 Valve train
At 2 min mark is example of why the switch in 2014s valve train on the fa20.

On the 2014+ they lenghthed the valve to make the notch on the rocker deeper and also made the pivot socket deeper into the rocker arm. This holds the rocker in place better at high rpm, valve float and valve bounce.

I read the camsafts were changed in 14 but I'm not for sure.
