Help identify aluminum heads

I'm still working on finding out what is actually in the motor , but would you agree with a 950 carb & 4.10s ?

The gears are probably the last thing I’d change.
And if it’ll see regular street duty, I’d run the tallest gear that would still let me reach my ET goal.

I’d be looking for a carb with a Venturi diameter of 1.400 or 1.450.
Pick your favorite brand.
