Yup, sounds like head gaskets. I had exactly the same thing happen to mine, I used Cometic head gaskets, retourqued and all. It would push coolant to the reservoir only during hard runs. I'll post a pic tonight of what the HG looked like after we took it apart. Both gaskets showed leakage of combustion gasses. The strange part was, it never did it when driving normally.

After every session / run with the car, I would let it cool down, then pump the coolant back into the radiator.
