It depends on the dome you use in the cylinder. If you use a lower compression dome you can use regular gas. Im pretty sure when you pick up the kit you can pick which cc dome you want.

This is straight off the website. It says it comes with 2 different domes for the cylinder head. Im sure that one would allow you to use regular gas and the other is a high compression one for race gas.
