Quit the G.D. whining and build something capable of your goals!
Like you have been told, no reason the foundation of what you already have can't reach your goals.
I mean sh!t, look at HardcoreB. He outperforms you all over the map, and he did it with less displacement, less compression and a set of SR heads.
If you don't have the knowledge to figure out how to reach your goals yourself, then employ someone who can, but catalog camshafts and 440 source valvetrain isn't going to get you there
