Howards or Hughes Camshaft

It's about time for me to make a few changes to my engine and I'm leaning towards the camshaft. I have the Diplomat engine equipped with the "302 casting" heads and hydraulic roller camshaft. Its daily driven and hurt feelings too :D My goal is to increase performance without throwing my combination off. I know Hughes have a real nice idle which I love, but I also love performance. Can someone guide me to the light?

My current setup:
Edelbrock 750, Weiand Action+Plus Manifold, Ram Manifolds with 2 1/4" Pipe and 4" Glasspacks, Mallory Unilite, Summit Coil, Factory High Stall Converter (A904), 3.55 Gears, 26" Tires
