Recently purchased an 01 Buick regal for a good price but needs the intake gaskets and valve cover gaskets changed.

So i have a cast aluminum upper manifold I pulled at a u pull it a while ago and I plan on replacing the plastic one on my Series II when I do the LIM. I know I need the Gen V to L36 TB adapter but is there any difference with the upper intake gaskets? There's 2 different part numbers for the Series II and III (FPG MS95812) and (FPG MS96691) will either one work?
