    Is the anti-freeze rusty, could engine need flushed? If it isn't coming out of radiator are you having to add any periodically? Could mean it's being puuled into cylinder during inake stroke.
    One way to check for a bad head gasket is to fill radiator up to neck, start motor and watch for bubbles getting increasingly larger and more frequently. Engine should be cold of course.
    Is there any reason your not running a stock housing? I can't lay off the thermostat need because it caused me to go through everything before I checked the most common. Even after a greybeard told me to change it.

    I had a similar problem on my 235 55 chevy. The radiator was crudded up inside. Chased my tail on that for a couple of days.

    in 1970 i built a water pump system for
    the current drag car...
    it was a one only configuration that would only
    pump the fluids when i flipped the on switch.
    and it was set up for some of the fastest 5 gallon water exchanges
    in the pits.

    Water pumps cavitating. Change out that bottom hose. Or put a coil in that one.

    Have you tried to take the upper radiator hose off the radiator, get a water hose, seal it inside the upper radiator hose turn it on full , see if you get good flow out of the upper radiator hose connector(since you don't have a thermo)....
