IMO:
You need more gear for your setup. A dual plane intake would be a band-aid at this time, but that will not cure your root problems.
The big issues I see are:
C6 tranny, it's tough, but absorbs 2x's more hp than a C4. You are losing 20+ hp at your wheels. Worse yet, the heavy internals in the C6 sap even more torque.
The cam you are running requires more gear, the issue is magnified even further with the C6.
The Torker 2 intake is not a torque friendly intake. The plenum is large and the runners short. It is one step away from a Victor Jr.
If you feel you must go to a dual plane intake, consider the F4B or the Stealth to be the only worthwhile choices.
A Torker 289 or X-Cellerator would be best, combined with a loose converter, and 3.50/3.70/3.89 gears (you pick).
If gears and/or converter are not an option at this time. You might be best off to use the bandaid, F4B (or one of it's many versions) or Wieand Stealth intake will help you some. You are on the right track, the Torker 2 is not a good intake.
Good luck
