    Thumbs up Has anyone done the roller rocker upgrade?

    I'm wondering if anyone has switched out their stock rocker arms for a higher ratio roller rocker on their LS2 motor? If yes, what HP improvements did you see, was the job easy enough and striaght forward?

    I did a Roller Rocker change on my 94 Vette LT1 back about 10 years ago, just looking to see if things are about the same these days.

    Its been done, look under the vette section,depending on mods,I would check pushrod lenghts,im running l92 heads ,they take offset rockers,used to do this on the old sbc motors and pick up some power on the exhaust side.
    mods: custom built twins, built 408 w/l92 stock GM heads,GM matching intake,drag bags,frame ties,aluminum drive shaft, performabuilt 4l80e,Yank converter,ohios fastest and quickest 04-06 GTO 9.52 at 144mph. 1.50 60ft on stock rear end and shafts/suspension,on drag radials.
