Oil burn cloud on engine deceleration

So here is a question related. For two of the center bolts I have to use a small 3/8 box wrench to tighten the bolts. I have used my arm torque wrench to get it where I think it is.

Anyone have any ideas as to how to really torque these bolts? They are ARP bolts with 12 point heads. I can’t even get a socket with a wobble elbow on them.

Maybe I should switch them out to a standard head and use my crows foot end on them?
You need a torque adapter:
