I am not vouching this will work in practice but if you can increase the redline somewhat there should be a lot of HP to be gained.
Recall the classic equation for SAE units HP = torque * rpm / 5252.
One thing that would have to be done is to decrease the intake restriction somewhat. While this provides a lot of mixture motion at low rpms in the interest of improving lugging torque, the features that enable the mixture motion cause flow restrictions as the engine runs faster.
One would likely not be doing themselves any favors in the durability department by running the engine faster though...
