Some JDM manifolds have TGVs and some don't. Besides that there is no benefit besides the red pimp factor.

the v8 intake manifolds are reported to flow more evenly across runners. this is supported by the fact that the v8 engine comes oem with 4 plugs in the same heat range, whereas the v7 does not.

Exactly. I believe it is the #3 runner that is a bit longer then the v7/usdm manifolds. BTW I have the v8 manifold on my car and it seemed to soften the bottom end a bit, but makes up for it with flow in the middle and up top.
