Lotsa luck...
Unfortunately, whoever installed that didn't think about taking it out. I'm sure they used an open end wrench at an angle, which explains the apparent rounded corners. I suspect you won't be that successful backing it out.
Failing the open end, you can try a flare nut wrench or even a box end. Consider sacrificing one to the cause and grind the wrench to fit. Once out, throw that bolt as far as you can and replace it with an allen head bolt.

Even an Allen head may not fit that location, I ground down the perimeter of an Allen head to fit there and it still rubbed on the intake runner.
If you can't get a wrench in there at all I would try a dremel or angle grinder w thin blade and cut a slot in the top of the bolt then use a big flathead screw driver or tire iron depending on the slot size and then turn it out, I don't think it will be in there that tight based on the access to it.

At least the bolt has correct markings. You could always weld a bolt or some provision onto it for a grip if all else fails.
Once your finished exercising your pitching arm grind yourself some clearance around it.

You could drill a 3/16 hole in the centre of that bolt down as far as possible. At least 3/8 deep, then use a screw extractor bit if all else fails. As others mentioned spin the SHCS down to a diameter that will make the next bolt install much easier.
You'll get it out, just be patient.

Open-end wrench used straight down from the top. Use a screwdriver or dowel of some type as a T handle through the boxed end. Turn the bolt head one flat at a time. Works fine, takes long time!

I ground down the two runners that run close and then sandblasted my intake to make some space on my RPM. Try a propane torch to heat that thing up, then try turning with an open ended wrench.

thats the reason they sell those special small 12-point headed inake bolts. Allen cap screws are just as wide and wont work any better than a std hex head bolt. You may even have to dremel it out down there for a decent fit or if you want to use a washer.
