It's definitely a factory thing. Everyone open up your How to rebuild small block Chevy LT1/LT4 engines book and look at the picture on page 137 (if the picture above is not enough proof). It ain't no secret hole put there by some yahoo with a drill.

sorry about the confusion everyone i meant to put up more pics but got side tracked haha, since it is a plug and obviously appears to be leaking a bit, is there a place where i can buy the plug in question? thanks for the help btw, because i had no idea what was going on lol

the head cover's half of the hole so there's no way the plug could back out, and if it was missing you'd be losing a lot more oil. just put new sealant on it if you're taking the heads off

Na it cant be a plug.
looks to me like that would be the oil port to keep the rear of the intake/trans bellhousing/anything under it well lubricated. I beleive GM did this to cut down on rust in those areas.
