Is there such thing as a good lifter?

He said this:
"Everytime we tested the standard Rhoads lifters, we lost top-end power, and picked up a little torque, but the power curve fell off much earlier then with standard hydraulic lifters.
Now, with the new Rhoads V-max lifters, we're seen great results.
They increase vacuum down low for racing classes with vacuum rules, and they'll hold the power much longer then a standard hydraulic lifter(we didn't see any change in low-end power)."

Also I noticed that he said "standard hydraulic lifter". So I guess you could draw your own conclusions from that.
