Default Oil leak help

I did the tranny fluid on my 1998 Corvette today and discovered an oil leak. Oil on the exhaust and bottom of bell housing and oil pan.

I went looking for the leak and it looks like is coming for a spark plug hole. I don't get it. But I have included a couple of pics. Welcome to suggestions or info where the oil is coming from. I am pretty sure the head gasket is not leaking. It 165k on the motor and has good oil pressure.

The leak is on the driver side and seems to be plug 5 and 7.

Thanks,
Dan...

Pull the spark plugs, if you can, run a compression test on those two suspected cylinders. My money is the head gasket.
