The heater cores were added when I added the oil cooler, a few months ago.

You added cores to the bypass hose? It's not a bypass hose in that it bypasses the thermostat, it's an anti cavitation line. With a restriction in it, the pump will cavitate and this severely affects pumping volume, even completely stalling flow. No wonder you had those funky readings.

Yes I added heater cores to the bypass line to add some cooling.

It was recommended to remove the bypass line all together when I tried to remove it the temps would swing. The thinking here was a lot of hot water was bypassing the radiator and could be adding to the heating issues I was having so removing the bypass line would force all the water form the engine to pass through the radiator. Well along the same lines I added two heater cores to the bypass line to allow some water flow but to also add some cooling along with it. This seems to have caused enough disruption in flow to cause the pump to cavitate.

After I put the bypass line back like it should be the temps form each head are within a couple degrees of each other.

Sounds like it's all sorted out now! The next trick is to see how it works in August with the A/C on and in traffic. That's what I'm waiting for, if it stays cool then, all is right with the world!!
