Well it seems I got an answer as to why I overheat after replacing the radiator and cap , hoses and coolant, waterpump thermostat and both cam positioning sensors. I took it in and was told I needed the heads done. What should I absolutely do since I only want to do this once parts wise ? In the future I am looking at adding some power somthing like a banks pedal monster or something nothing real crazy. Thanks for the comments.
