The reversion can be limited by a good valve job. Also having the intake slightly smaller than the head so reverse pulses get hung up a bit. Lash will make almost no difference at only .002 tighter.

Just thinking out loud, but perhaps the Vic JR is too big for a 350, compounding the signal issue to the carb? Maybe even smaller headers that might scavenge better around 4000rpms?
