I was wondering if putting in new reeds and running race gas will cause me to have to change my jetting? And if so what will it usually do? Richer or make it leaner?

Unless the engine has been modified, you don't need race gas. Some race gas is oxygenated and some is not and both will burn slower than 93 oct pump gas and could cause jetting issues.

You will have to rejet for those changes. Boyesen requires it and i would assume vforce as well even tho they dont say. And you need to rejet for the fuel too.
