Sticky injectors

Hello everyone in 5.0 land. I picked up a 89 notchback to use as a daily driver and one of my injectors makes a pretty loud ticking noise. It goes away when I unplug it. I have the stock injectors from my bullitt and I was wondering if they would work? They are the same orange color on top and the connector looks similar. Thanks in advance for your help.
 
it might be possible it could be a exhaust leak on that cylinder? when you unplug it, it would make no explosion so you wouldnt hear the exhaust leaking out...if it was the case, just a thought

I never heard a injector anything like a rod knock, especially overcoming the sound of the sound of exhaust, fan, and everything else coming from an engine...just my 2 cents
