Are you using coolant or only water? Also, I need you to check some things. First, is there any coolant mixing with the oil? Any oil mixing with the coolant? Also, check the front corners of the cylender head for evidence of coolant leaks. Finally, with the engine cold, remove the radiator cap and start the engine. Does any of the coolant come shooting out?
Sorry for all the questions, but based on what you replaced, I really am thinking you have a bad head gasket and that is causing the problem. If coolant is forced from the radiator when it is cold and you just start the engine, that tells me compression is making its way into the system.
Let me know what you find. Also, check closely for evidence of leaks around the head. Most common spot is the driver's side front of the engine for leaks.
