Depends on your power curve. Everyones is different, whether its a NA cammed motor, centri, KB, etc... Reason the 4V shift higher is because the 4V heads are a lot more efficient and make power to 6500rpm. A stock 2V wont maker power past 5500rpm.
My car on my first dyno didnt drop off power, and revved to 6400rpm no problem. So I set my shiftlight at 6300rpm so by the time I shift its probably 6400rpm.
The last time I went to the dyno it stopped making power at like 6100rpm which was weird.
