Well i go to start my car after the carb swap set timing everything is well but my 4309 return style regulator slowly drips droplets of gas out of the 3/8 npt fittings. What can i do about this?

Teflon tape. Mine did the same. Just wrapped 3 layers of teflon tape and it went away no problems!

i prefer teflon paste, that way it won't get into your fuel system and clog up like the tape potentially can do

all paste is non hardening, but loctite is usually what I buy, it's in a white tube and is typically used in industrial settings.
