Lighter valve springs = more horsepower?

According to Comp, every gram of weight reduction in the valvetrain adds 30-40 RPM potential to a motor. Obviously the rest of the motor has to work to take advantage of the additional RPM, but its pretty surprising how many combos are valvetrain limited.

Further, a lot of the pressure of a spring is required to control its own weight. Lighter springs, less pressure required, less drag on the motor.

Beehives have picked up everything I have ever put them in. But its important that in the quest for lighter weight you don't skimp on the pushrods. Thicker, stronger pushrods are always better.
