With the new Comp cam they recommended with the Rhoades lifters should bring the power band to 1800 -6200 RPM.
It took 3 years to convince me to use these, but now that I started, it's all I use. Even if the cam comes with lifters, I buy a set of Rhoades. They work and also make the engine easier to tune as it runs smoother at idle than with regular lifters.
