1. Yes.
2. The LS2 timing cover has nothing to do with deleting the DoD.
3. Why get a drop-in cam and then change valve springs? If you're going to be changing springs, why not get a more capable cam?

the ls2 has the cam sensor on the timing cover thats gonna be needed when delete the dod cam and why would anyone reguild a engine with the same valve springs? and this is a daily driver not a hot rod or race vehicle so the cam i picked is great for what i want to do

If the engine has DOD it already has the late timing cover with cam sensor. One look would tell you that.

To fully delete DOD you need 8 more std. lifters, a full set of lifter trays, and an LS3-type valley cover.

I THINK the PCV system is the same between DOD/non-DOD engines. So no PCV changes as far as I know.

The three bolts applies to how the sprocket bolts to the cam and has nothing to do with the cover.
DOD relates to the cam, lifters, and valley cover ONLY.
VVT is related to the cam, sprocket, and front cover ONLY.
The front cover is changed ONLY when converting FROM VVT to non-VVT.

If he is changing from VVT to "normal", then yes a "normal" non-VVT cover is needed. A 3-bolt conversion is not what necessitates that however. 1-bolt cam non-VVT engines have the "normal" cover, and when switching them to 3-bolt cam, no cover change is needed.
And no, I don't do this for a living. I have studied LS engines for the last 4 years until I know just about every nut and bolt on them.
BTW, ALL VVT cams are single bolt whether aftermarket or not. They use the central single bolt to pump oil into the phaser.

Not unless he is deleting VVT.
