Can you get just that valve or do you have to do the whole assembly?
Generally the feedback on the new plenum is that it won't really give you any benefit unless you're up around 600 whp/wtq.

If you are replacing the plenum you might want to think about doing the 997 intake manifolds as well. I believe this is what Protomotive, Switzer, etc are doing with all of their high power builds. I also have a fresh set for sale in the classifieds if you are interested.
