Does anyone else have super loud ticking injectors, any ideas is this bad? ideas on replacement?

 

i swapped mine to the ford ones in my signature (not yellow sticks) and i hear them clicking. I didnt really pay attention before and didnt notice until i was driving without a hood for a while. Im guessing its normal but would also like to know for sure

 

mine tick quite loudley.. had my step dad check it out, hes a mechanic and he says they are fine. his ford v-10 injectors tick too.
