Are you running this test while cranking the engine? If so, and there is a compression difference, the cylinders with good compression will draw more battery voltage away from the ignition, showing as a weaker spark.

There is no possible way a plug screwed into the head is not grounded.
Even a totally fouled plug will still draw a spark from the wire, it just won't ignite the fuel.
Any possibility some of the plugs are resistor plugs and some are not?
