all good advice, but if you were changing/messing with hoses, and as you say, you are not sure if they are right, it could be your thermo bypass hose is not routed correctly. You stated you ran a hose from intake to block? There should be one hose that runs from the water pump side of the thermostat housing up to the head at the larger water tube on the intake manifold. It circulates water between pump and head until the thermostat opens and the entire system circulates.
