stock stamped rockers spec out at 1.52 or soemthing like that, but they are said to vary from 1.45-1.55 or so.
since you are buying parts, and if your cam isnt' already too big, then get some 1.6 rocker arms. the cost is the same, but it does add a bit of lift and a few degrees of duration to the cam that's in it. if your cam is .450 lift with the stock 1.5 ratio, then it will be .480 with nothing but changing the rocker to 1.6.
