Strange how the passenger side #'s are consistently high, and the drivers side are low. Do you have the identical heads on each side?
Any chance throttle plates closed when you were doing driver's side?
If you have dual exhaust do you have oily soot in driver's side tail pipe?
You seem to have 2 problems, a bad valve on the driver's side and a mysterious low pressure on all driver's side cylinders.
If you get hold of a leak-down tester, it works really well at pinpointing the problem, especially the bad one - rings, intake valve, or exhaust valve. It needs a compressed air supply. You pull each plug, connect air supply, and basically pressurize the cylinder. Listening for loud hiss at carb, exhaust pipe, and dipstick tube pinpoints if rings, or which valve is leaking.
