Intake manifolds how 454 rebuild

Love to hear everyone's experiences and preferences on an intake manifold for my 454 rebuild. I'm running comp camshaft Hydraulic Flat Tappet, Duration 292/292, Lift .550/.550, 110 lobe separation with comp magnum 3/8 push rods, comp high energy rocker arms, Holly 850 cfm carb, MSD pro billet distributor with 6 AL box. Last piece of the puzzle is the intake. Thanks all.

What about the rest of the engine ? Heads, compression ratio etc. All of that comes into play. Also how hard do you plan on running it.

Last year I tested 3 dual planes and 3 Single planes. All within a couple of tenths of each other. The winner was the old Team G oval port followed by the Weiand Street warrior small port in 2nd.
