That cam isn't what you want. Way too much duration, not enough lift. You're going to want to be in the 0.850" range on lift, and 288/296/108-110 on duration, you need a custom for what you're doing. A good tall single plane single 4V intake will do fine. I'd use a big 4150, maybe a 1050 with annular discharge boosters, talk to Trevor Wiggins at Get'Em Garage.
You're going to want T&D or Jesel rockers, 1.75:1, or maybe 1.8:!, depending on the cam, and I'd use Ferrea hollow stem valves, the Comp 1.560" dual spring and tool steel retainer, they have some of those that are lighter than a triple spring with titanium retainers, and they're a better spring, higher quality material and finishing.
