You're thinking of the VSV (vacuum switching valve) that goes to the EGR. that needs to be blocked off. The other VSV is under the intake and goes to the FPR. The BVSV (Bi-metallic vacuum switching valve) is on the water neck and that goes from the TB to the charcoal canister. That is what you're going to be using.
I honestly don't get all the fuss about the vacuum system on these cars. It's fairly simple..
