Heater vacuum fittings
I took my a/c off the firewall because it didn't work and I want to know if I need the vacuum fitting that is behind the carb on the intake manifold? I was planning to run my PVC to that port if I don't need it for my heater.

As long as the fitting is 3/8 in in diameter at the carb base plate or below you can use it for your PCV

Yeah, into the base plate of the carb is fine. May be better to put the power booster to that port, if its tee'd off something else.
