Please check your processors, logicboard and power supply first to make sure the leaking didn't affect those parts. To do so, there are steps on this site that will show you how to take these parts out and then check them to see if there is any corrosion. If there is, you will have to replace those parts that have been affected.
If all is good and no parts have leaked, then you take out the LCS unit with the processors as a whole. Unscrew the 8 logicboard/LCS secure screws. Pull out the LCS unit. Then you remove the processors from the LCS unit itself by removing the 12 - #1 Philip head screws and the 8 Allen head screws securing the processor to the LCS unit.
Then carefully lift the processors from the LCS and set them on a static free surface. Then you will want to clear off the old thermal paste with afterwards clean with rubbing alcohol to make sure the surface is really clean. Don't worry about taking off the single heatpipe that is on the rear of the processor, this will not stick past the original heatsink.
Then do the same with the Heatsinks from the parts machine you acquired. Attach the processor to a heatsink and then secure the 4 allen head screws and tighten them like you would a car tire. once they are snug (not over tightened) then you can screw in the 6 - #1 Philip head screws. Repeat the same process for the second processor.
Now take the processor/heatsink combo and put it in the upper most logicboard/processor slot. Push firmly but not overly hard until everything is snug and connected. Once this is done, you can screw in the long allen head screws that secured the LCS to the logicboard. Repeat the same process for the bottom logicboard/processor slot. Then you have a pair of processors that are now air cooled.
Put in the plastic flow cover that came from the heatsinks, not the LCS unit (that sits right on front of the heatsinks) and then put in the front fans, then the Air Baffle, then the side cover. Boot from the AHD 2.5.8 and run "Thermal Calibration". If there are no issues, you can now restart in OS X with your new air cooled G5.

No badge, just a true answer. That's what i am seeking.
Two hours of web searching on this netted nothing on swapping out. I don't see why the AHT wouldn't work or the Apple.Service.Diagnostic.2.5.8
in case anyone was wondering where the info went, my site was taken offline and moved to a more secure server. the new site link can be found here @ http://tinyurl.com/jg398v5
Can you perform this air cooled mod with a late 2005 issued G5 2.5GHz DC using the heatsinks from either a 2.0 or 2.3GHZ Dual Core G5 PowerPC?
