unsticking throttle plates
The problem you have is rust between the throttle shafts and bushings. If you get it move a bit then keep spraying it down it will eventually loosen up BUT, now you will have air leaking in at the throttle shafts due to pitting. This and bent throttle shafts from an over zealous throttle foot and over tourqing the base are the big reasons why "My Holley doesn't run right".
Just get a new throttle body from QF and avoid this problem. They are a much, much nicer piece than stock, are carved from billet aluminum, have a thicker base plate, have teflon coated shafts (to prevent rust), have streamlined throttle plate screws, the blades are stainless steel and they have an easily adjustable secondary idle screw plus come with a linkage kit (super progressive, progressive and 1:1).
The best part is that they are made in the USA and run about the same price or a few bucks more than holley replacement. JMHO
