781 head bolt question

I have a pair of 781 heads on a 454. It looks like one of the head bolts are sunk into the head? In other words the bolt head is flush to the surface of the head. Someone machined the bolt hole and widened it for whatever reason between the #8 intake and the #6 exhaust rockers. Does anyone no why someone would do this? I would post pics but the server is down.
