RPM Airgap vs. non-Airgap?

Oh I could live in Vegas all the time--If I had thousands of dollars to spend each and everyday!! :headbang:

On that racing gas--I went on Google and you can buy racing gas shipped right to your house from a few companys. 5 gallons or a barrel or even muti-barrels--I think each barrel is 55 gallons. They have all types and have how many grams of lead each gallon has. Did not price it but I think its up there. Sounded like it was no problem to get as long as you have the cash.
