That cover is what the factory ran on vehicles without DOD, so you don't need to do anything other than install that cover. People usually do both, but I've run just the cover on a few vehicles now with no loss in oil pressure.

I have no idea why but nearly every time I take a LS apart with higher miles I find the two rear bolts on the valley cover looser than the rest often finger tight for that reason I like to plug the towers either tap & install pipe plugs if it's bare block or use the rivets that Lingenfelter has if it's still together.Along with the cover just for insurance.
Summit has them they do require a hydraulic rivet gun to install.
