If it was the gasket would'nt I see the other signs? Oil in the AF, AF in the oil, white exhaust?
Not necessarily. Exhaust gasses are probably leaking through the HG during combustion, and coolant may not leak back into the combustion chamber. Just because exhaust is venting into the coolant system, doesn't mean that oil and coolant will mix either. The only oil that would make it into your coolant system in this type of leak would be blow-by from the rings, and it's such a small amount of oil that it would be hard to detect.
If you let the car sit, pop the overflow bottle open and there's a rainbow-like appearance floating on top of it, that's oil. You may not find chunks or obvious signs of oil.
You should get your radiator pressure tested. That would be the easiest way to tell if you have a bigger problem, but from what you've described already, it doesn't look good. If you have all the right tools (torque wrench and preferably some air tools) you could do this job yourself in a day for the cost of a set of head bolts and a gasket. That's under $100. A shop will charge you at least a grand. It's a lot of labor.
