Need holley 4bbl jets

On my '77 F150 with a 460 auto I recently picked up, the previous owner installed a Holley 4160 (essentially the same as the 1850) 600cfm 4bbl carb (vacuum secondaries, electronic choke). This was back in '83-'84. Even though I've sprayed carb cleaner and ran a tank of Techron thru it, adjusted the floats and idle mixture screws, she is still running very rich - the spark plugs are very dark colored and the exhaust pipe is still black. I have purchased a holley "refresh" kit which has all the gaskets, power valve, etc in it, but reading thru the Holley tech manual it suggests that I may need to lower the main jets based on my plug color readings. I don't want to go out and buy another kit which would be a full "performance rebuild" kit ($$), and was wondering if anybody has any jets laying around from their previous rebuilds that they have no use for that I could try??
