AFAIK, the specs you want don't exist in an off the shelf solid roller cam. I'v searched, and haven't been able to find one from any manufacturer.
The wide LSA is important for Webers, or any IR intake system. That keeps overlap to a minimum. Since you don't have a common plenum, the overlap will create the fuel cloud from reversion.
I rtan a cam similar to this one (hydraulic roller) in my 427W. It makes great power, and pulls like a freight train all the way to red line. It makes power pretty much everywhere.
Use caution with your head selection. I'm using some Dart Pro-1 195 heads. They have a 2.02" intake valve. A couple of years ago I tried a set of Brodix heads, with 2.08" valves. I lost all my low end torque. The intake was too big for the throttle body, and the intake charge lost it's velocity. The intake valve should not be larger than your carb/TB bore.
Your carb bores are 48mm. Your intake valves are 50mm. You might have a mis-match there. The blades and other stuff do take up some space, so you might be OK. If you haven't purchased your heads yet, you might reconsider that choice.
