However I find they run total different.... I personally was not a huge fan of the Stage II on a customers boost 306. With your combo I would go custom to get the most out of your combo, power and streetabilty, but unless the AFR are the brand new models you'll be swapping valve springs and seals...which is a good idea anyways. I recommed you go to
www.flowtechinduction.com Ed can get you a nice cam, and valve train package.
