No, it needs to be a little longer, but the exact amount will depend on the rocker ratio and the position of the adjuster ball or cup. A good guess would be the height of the shim multiplied by 2.76/1.76, or about 1.5. So if you are shimming the stands up .040", the pushrods needed to keep the adjusters about where they are would be .060" longer. Of course, that additional .020" is not more than about a half a turn on the adjuster, maybe not enough to worry about...
