It seems like we aren't looking at it from the same perspective.
With mechanical valve timing, you cannot change the lift or duration.
With electronically controlled hydraulic actuator, throw out the rule book. Notch the pistons, and you can leave them open 360*, if you like.
What I am thinking, is you close the valve well before tdc, you reduce the amount of air drawn in. Now your 350 running 11: 1 static compression is developing cylinder pressure no greater than a stock 8:1 compression motor.
The valve overlap is modified, your 11:1 motor is running smooth and docile, you can even pump low octane so save $$ on your daily commute. Then tank up with av gas, drive to the track, flip a switch, and the beast rumbles and crackles ready to make asphalt scream for mercy.
