Issues with heater hose routing??!!

I have never been able to get my truck to totally warm up. I replaced the tempeture sensor. Nothing. Checked the thermostat. None installed. Added a 195 thermostat. Now it warms up to like 1/4. the line between 100 and 210, so like maybe 150 or so. Then I checked the heater hoses. There is one coming off of the intake manifold, 5/8, leading to the heater core. A 3/4 comes from the heater core back to the radiator, right above the tranny fluid lines. Ok, so I have a constant flow of water through my radiator. How should I fix this. I do not see anywhere there should be a heat cut off switch. I am pretty sure I have always seen the return line going back to the water pump. I have an 86 silverado, 305/350. It has A/C, and heavy duty radiator option. What would be my next best course of action to unsure my motor is warming up to proper temperature.

thanks
robert
