If I were you...I'd worry more about the needle jets and jet needles. If they aren't OEM...you will usually be disapointed by the new ones supplied with the kit.
Thanks for the tip. When I did the rebuild, I only replaced the pilots and the mains, along with a bunch of missing orings. While the kits came with new needles, they didn't seem to be replaceable unless I pulled the completely rack apart, so I left the originals.
So anyway, I figured I'd start trying to solve this by putting the original mains back in first, since I never saw the plugs like that when they were installed. I'd put the old pilots back in too, but two of them were bent by the PO....
