Strange head issue. Casting?

I'm in the process of tearing down my VG33 for a turbo project and as I was involving the drivers side cam I noticed the area of the head by the rear of the cam had a hole in it. It looks like something wore through but there's nothing back there and the cam, washer and bolt had absolutely no damage. I'm assuming this was an irregularity in the head casting. Any input?

DEREK probably knows for sure but it looks like a core shifted during casting.  The machining operation broke through and the QA department probably had to give it  pass to let it through.  Just a guess.
