Also known as Active Fuel Management (AFM). I think you want to disable the AFM and get a regular cam and swap out the weak AFM lifters. I believe those are known to be the weak point. When getting more and more power, I would do things right.

DOD does shut off the valves. It does NOT retard or advance the timing. So that means that you can use any off the shelf 3 bolt cam.
There are no specific cams that are "just for" motors with DOD

If your motor had VVT it would do the above, plus . . . advance and retard the timing with the cam phaser, which you do not have . . .
