Ok...everyone loves using Wikipedia's highly informative LS-based but it and LS1Tech are not helping.

Am I correct in understanding that until the advent of the '09 Cadillac Escalade Hybrid LFA and '10 Escalade L94 no previous LS motor has had AFM/DoD AND VVT?

Also, for those with a bit more mechanical knowledge, am I to also understand that adding VVT to any Gen IV simply requires the hardware of the timing cover, actuator, VVT cam, and notched pistons?
