Dumb question

I am new to the mopar world (always had GMs) I just got a 65 Dart with a 318, not sure what year the motor is, but obviously not original. It currently has points ignition and a 2 barrel carb. I am going to upgrade to a elctronic ignition and put a 4 barrel Edelbrock 600 CFM carb with a Edlebrock performer intake. I am trying to find the intake gaskets and was wondering gasket you would suggest using and when swapping the intakes is there anything I need to be aware of I noticed 2 and 4 barrel gaskets is there is a difference in heads or just the intake? Also what coil would you recommend for a mopar performance electronic ignition?
