67 twin turbo dart

Well after talking with Matt at DIY I pulled the plugs and all were black, which I wasnt surprised since I have 160lb injectors, the wires ohms were 27-29.1 range on all the wires. I did forget to look up the proper gap they are .030 where the LS coils need .040. Would lower resistance wires help out this situation or should I drop the injector size? Picture of plugs and ohm readings are on the picture below. Course its hard to see the rear ones. Figured the not being able to idle was from being to rich, and still acting like misfiring due to unburned fuel.
