im doing my head gaskets and went ahead and had the injectors flow tested and cleaned. one of the injector cups came out with the injector, the rest stayed in but one of them looks just a slight bit higher then the rest. should i just put the injectors back in or pull the cup. like i said it stayed in when i first pulled the injector. and i didnt pay close enough attention to see if it moved when i pulled the injector. what should i do?
