I have almost the same identical combo. Mine can be daily driven. It's certainly a Friday driver.
440, eddy RPM heads, 242 cam, 950 carb, 456 gears, 3500 stall. Goes 11.70's @114
I wouldn't put a nickel into iron heads. Go aluminum.
That combo may touch the 11's with a decent stock replacement head. It won't go low 11's unless you have some impressive heads on it. Even then the tall gears and low stall are going to hinder you.
