My B20e is running rich, what to do? 140-160 1973

Indeed Rhys, I did install a new header, and ran it for a trouble free week and a half before experiencing any problems. The initial circumstances involved me running dangerously low on gas and the car dying while going up a steep hill. Total loss of power and then dead, wouldn't start. I get gas, the car starts after I goose the throtle a little, but still no power. After I get were I'm going, I look under the hood and find the wire for the #2 temp. sensor/ coolant sensor had worked lose. No big deal, plug it back in. Except the plastic plug had become brittle and desintergrated, so solder the female spade conectors back on. And that's were it stands.
I've checked the wiring, and replaced the temp. sensor. I've checked the MAP sensor and it's wiring (ohm reading of 91 and 340 for the wires and sensor). I've checked for a maifold leak and replaced the manifold nuts, while retaining the washers, and wrenched the nuts down (is there a torque setting I should be using?). I've pulled the gas return hose from the pressure regulator and have blown through it to check for a blockage. I've even adjusted my voltage regulator to lower the voltage, on the advice that too much voltage will cause the ECU to preform with the symptoms I have been experiencing.
Whew. What else is there? I understand some adjustment can had on the MAP sensor, I'll try that next. So, I'm not sure it's something simple, though I wouldn't be surprised.
I appreciate your advice and insight, thank you.
Jonathan
