Valvetrain weight vs. RPM limit

MADIRISHMAN said
The weight is not the key factor ,rolling resistance of the valve train is the key to higher RPM and getting to the RPM quicker.That is why a roller set up is far superior then a stock valve train for longevity and the speed it takes to get to your RPM limit

I agree, key is how fast it revs for better valvetrain components. You can bring it to a higher rpm without float, yes. But not every combo really needs to, or can make better power up there. But they will allow it to rev up faster.
