I read somewhere that it is actually better to keep both VRIS points open past 6k rpms on a ZE for best airflow. If you only rev to 6.5k, then this is not a big deal, but for those that go to 8k it was said to make a difference.

Not possible, the Kl engines stop making power at exactly 6200 rpms doesn't matter if your vris is open or shut. so those reving to 8k rpms on stock blocks are just hurting the engines and they need to learn to shift lol. Just because your in higher rpms doesn't mean your making more power, and if you shift at 6200-6500rpm range it will drop you right back in the sweet spot that the kl's love to make power at.
More power can be obtained past 6200rpms but this requires a lil work to the motor

Well, I didn't say it'd be making more power, but you are right in the fact that there is no point on a regular ol' ze.
W/ full bolt ons and cams though + megasquirt there is plenty reason to want to rev. that high, especially if you've changed your tranny. You can still make HP past your torque peak, it won't be as efficient, but it will still work!
