Small hole in head at bottom of valve cover bolt!

It looks like it's broken out so a extra long bolt was put in and cranked down at one time. I would just use a little sealer and call it good.

Thanks Mike. I have no idea how long it's been like that but it's never been an issue that I know of. Do you mean sealer on the valve cover bolt to keep everything inside the head or should I try to seal the hole?
