it does depend on that you most likly will be running race gas

In most, if not all, areas of Kentucky you would need race gas with 18's

Thanks For The Reply! I Bought these used off a friend, or i would have bought noss heads, since you support the HQ. Is that much compression going to effect reliability? thanks Again!!

I'd worry a little about a stock crank with 18's. A lot of people get away with it. "Do you feel lucky?"
