How many times do I have to type it in here? There is only ONE WAY to find a small leak in a head gasket!! That is to fill up the coolant system and keep it full while watching the top level for bubbles while ideling!! It takes all of five minutes and is 100% correct!
If you are too full of yourself to go out and DO IT you will have this problem for a long time...won't you?
You have already found that simply THROWING PARTS at a problem is NEVER the answer.. One must first analize the problem and find what needs to be done before replacing ANYTHING!!
