on my blaster i have a 35mm pro design intake manifold and want to get new set of reed cage. on the pro design intake there is a valve or butterfly that splits the air flow into 2 channels. if i remember right the butterfly thing sticks out toward the reed cage. would the delta vforce 2 or 3 reed cages fit the prodesign intake. only thing i could find for fitting issues was with the boyesen rad valve intake and the delta not the pro design.  

i think they make v force reeds and cage to fit your intake.
