loud injectors?

[SHIFTrl240]

after getting my distributor back in, and before i have had the time to grab a timing light to get the timing perfect i have noticed that my injectors sound very loud... like a tick tick tick tick i can hear every one inject or whatever. im pretty sure it is the injectors since if i unplug one it goes to a tick tick -silent- tick until i plug it back in. is this normal or could it possibly be from more load from the timing being off slightly? (if thats possible) it runs and drives fine, just i have been really picky on my engine noises and been hunting down the problem. i don't want it to sound like a truck :/ thanks for the replys
