I bought a set of Venom Injectors for my LT-1 anyone know much about them? I bought off another member and they are supposed to be new, I tried to install but the groove for the injector retainer clip doesn't line up (it's higher on the injector than the stock injector groove) and 6 of the injectors have a dark blue tip and the other 2 are light blue. Is this still a matched set?
