Worst case would be loss of Heat Treat. You can check by doing Rockwell test on the castings, it is non destructive and verifies the hardness of the material. IF they got REAL hot they CAN lose their integrity and dimensions begin to change. Valve seats and guides can get loose due to dimensional changes & loss of press fit between components. This is the thing to be concerned about.
