Not trying to argue, just learn.

I thought the advantage to a roller cam was the fast ramps that open the valve quickly to full lift and hold the valve open at full lift longer before quickly closing the valve.
The result is bigger broader power/torque curves and higher overall numbers. Making only an extra 10-20 peak power and torque isn’t the whole advantage the extra power is through the whole rpm range and both aspects help acceleration and drivability.

Also with stock heads it would matter less, but if you have good flowing heads the roller advantage shows up more.

Is my understanding wrong?
