Should i de-smog?

Hey guys i have a 75 dart swinger 318 Ci California car. I live on long island and emissions here are not as strict for older cars. I plan on replacing the 2bbl with a 4bbl when funds are available dont know when that will be. Going through the engine i found a lot of old hard cracked vacuum lines that i have started to replace. I know the AIR pump does not work so that will come off the car has custom exhaust with no cats so AIR pump is not needed. can anyone give me an idea what can be removed to start this DE-smogification? I was a Chevy guy (still have an 87 MC SS Aerocoupe) so i know what can be eliminated from a gm car with no problems but these mopar things im still new at. Thanks for any help
