You should use at least a 7.0" long connecting rod in which case the block deck would need to be extended.
You could consider oven brazing a new block deck to the old deck that has the correct head bolt hole locations and water holes.

Once you go past a certain throttle position and absolute manifold pressure the system goes into open loop mode and no longer looks at the O2 sensor for compensation.

There are three parts that valve the fuel coming into the carb, the needle the seat and the floats.
you replaced the needle so either the seats have a problem or something is keeping the floats from floating upwards and closing off the fuel.
