***UPDATE***

So I tore her apart and when I took the thermostat housing off the engine I could clearly see that it had corroded and was in pretty bad shape. I put a new thermostat and housing on, bypassed the little coolant line to the carb (it goes to a small block of metal to help heat the carb auto choke mechanism as far as I could tell) because I am in Cali and it is never cold here, flushed the entire system out with 50/50 vinegar and water, rinsed her out twice, the filled her up with coolant, burp, fill, burp, fill, burp, fill.... And now she is a cool kat!!! What a freaking difference it has made now that the coolant system is working correctly.

Thanks for all the help guys!
