i already bought a thermostat, im just waiting to replace it after my smog check. a rad fan and motor is ont he way as well.
i already replaced the distributor, o2 sensor, PCV valve, plugs, plug wires, main relay and checked the injectors for clicking.
i run fuel injector cleaner every tank (have a whole gallon of mystery oil

OK, sounds like you have things handled. Where does the temperature gauge hover when driving around?
I don't imagine the radiator cap would be good. Put an OEM one back on and see if anything improves.
