Generation IV Internal Engine - Ly6 valley cover?

I was wondering does it matter if I use a Ly6 cover or an LS2 or 3 style cover. I have LS3 heads and a car intake and I dont plan on using VVT or anything like that?

On an LY6 block, you need to have a valley cover that has the oil galley o-rings to seal them off

If I remember correctly you can use any of the covers you listed, they should have all the o-rings needed to seal off the parts.
