Loosen each stud individually and re-torque to 25ft-lbs.
The chirping goes away after the engine warms up. It is the material directly below the exhaust port that causes the leak, there is no quick fix other than head gasket & surface.
But, it will do it again...
I ran my roadster to a perfect season in 2009 with a head gasket that leaked starting the first weekend. By the time the world finals came around, the leak was evident at idle when warming up but would go away when the engine got fully warmed up.
Run it, put your laps in it will be fine.
