Hot starting issues

So I have a 71 Dodge Dart with a 360 and mopar electronic ignition conversion kit. After I installed the headers I have been having issues starting the car when it has any sort of temperature left in it from driving where I was going. I’ve swapped the coil and ballast resistor today and I’m still getting no spark when the i try and start the car but get a spark when I turn the key back to what I assume is the accessory position (the last position before it locks up and you can remove the key). I’m getting fuel to the carb and the car starts right up first thing in the morning, just not when it has anything close to operating temp left on the gauge. What am I missing? Any help would be greatly appreciated!
