I've just gotten done installing the new Hurricane manifold.My setup is:
stock 225 w/ ported head
dual Dutra Duals
2 1/4 pipes to a 2 1/2 single exhaust
Locar kick down
Holley 390 vacuum secondary
14" drop base air cleaner.
2.97 open
I needed to do a some grinding on the manifold to get triangle washers to fit but other than that it fits well with the Dutra Duals. Much easier than My Clifford and the Dutra Duals. I also needed to use a longer throttle cable from a later slant six car... my V8 cable was too short but the Locar kick down worked fine. I did need to to make a new bracket to hold the throttle cable and kick down. It was a tight fit getting to all the bolts to torque to manifold correctly but I'll address that the next time I have the manifold off. Just a little more grinding on both intake and exhaust manifolds.
I haven't done any tuning on the carburetor yet, its new out of the box or even adjusted the timing yet but first driving impressions are good. The throttle response is very good, it easily spins the rear tire with my 2.94 gears. I was a little surprised.
There is good clearance with the drop base air cleaner enough that I could add a carb spacer if needed.

Are you running the (available) plenum heater?
Not going to work very well. Perhaps there can someday be a rev-2 version of the intake that has a gasket flange with drilled and tapped screw holes on the underside of the plenum, with a matching gasket flange on an open-topped water box. Or perhaps the water box could just be cast right into the plenum...
