the boysen rad valve vs. the v-force reed cage, which one do you guys think is the most bang for the buck?

 

I would go with 1 Dir Racing reed and cage set up. They are the best in my opinion!!!

www.1dirracing.com

 

from looking at different web sites it looks like the rad valve comes with a new intake manifold attached to it all in one piece, does it come like this?
what about the v-force, does it come with a attached intake manifold?

 

neither of them do. IMO v-force are better. Little better noticable power, and they dont break as easy
