custom cams...valve acceleration limit

[roortube]

So aIm thinking of having a set of AAN cams reground for more lift but stock duration and overlap. The variable is the rate of acceleration of the valves. Given a complete Super tech valve train and hydro lifters what's the consensus on the limit of Amax? This was also sent via email to super tech, but I'm assuming the limit will be with the ability of hydro lifters to pump up on valve closing.
