Default Holley 90mm TB on LS7 Intake?

Holley has come out with a new 4-bolt 90mm TB for LS manifolds. It says it fits the LS2 and the LSX intake manifolds, does this mean it will fit an LS7 manifold as well? I know this doesn't fix the excessive air to the #2 cylinder issue, but it's just another LS7 cable TB option. It looks to be around $430, much cheaper than the UMI TB. Looks like a nice piece of work too.

I heard the NW TB has clearance issues on an LS7 manifold.

the top of the cam needs to be ground some to clear the pcv line at the manifold on the LS2/7. no big deal.

or for an easier fix you could use thinner wall tubing from the nipple on the manifold to the pcv valve. i just notched the stock hose and works fine.
