Do you have the 96 or the 103? If you have the 96, I'd suggest the SE 211's. If you have the 103 (like my RK Police), I'd go with the SE 255's.
With your stage 1, both will give you in the area of 95-100 tq.
211's act like stock til somewhere around 2500, then they kick in and will run like a scalded dog. 255's are for big motors and torq early, kicking in at 2000 and pulling hard to 4500-5000, but still run hard to the 6200 max rpm. My buddies 02 RK had the 95" upgrade w/211's and ran like the wind. My 103 runs great w/255's. My .02 . Tracy
