RPM Airgap vs. non-Airgap?

It would be hard to make a perfect comparo. Many changes are possible.

Just try a straight up of whats there to whats being sought.
Things like, jetting changes should be included as well as,
60 ft times, 1/8 & 1/4 times and speed (Trap speed)
Also, if you could possibly included mileage.....

Have fun, good luck.
