    Whats your e-mail? lol I almost did mine too but last min change.

    I did the 224 cam and just change springs and PRs. So i dont think rockers are a must, but do provide so power if you have the cash to spare.

    you talkin 'bout uppin your ratio or just gettin roller tips? uppin your ratio too much would not be safe with the ls6 cam and stock bottom end. as far as roller tips you might free up 10 wheel optimistically. not worth the money unless you got some to toss around.
    -if you have a fact ls6 cam and up it to 224 duration you will see a healthy improvement. the factory 405 horse ls6 cam (which i assume is the one you have) has real lame exhaust--204 duration and 218 on intake. its hard to say what youll pick up but i imagine it to be 20+ wheel with LT's and the ls6's. be careful though, 98 and 99's are a 'lil suspect for rod bolt failure when spun high. i'd spend money on rod bolts before i got rocker arms. ya dont have to but i like to play it safe.
    2000 red ss: >2" drop, koni adjustables 'n 275 s-compounds all way around, giant brakes, dynatech LT's, borla catback (no plate), t56, tubular everything, HARD TOP, caged, "stock" heads 'n a mean cam. -2* front camber.
