Engine pulling time

Well, something horrible happened to me while I was installing my long tube headers, the very last top bolt on the far back side of the passenger head broke off.. . To answer any questions if I was pissed afterwards yes..extremely, the damn thing didn't even feel like it was tightening up, ist just completely gave loose, so now this week, i'm setting down to remove all the crap off of my motor to lower drop the k memeber out so i can remove the header and attempt to remove the broke off bolt without having to drill into my engine. If anyone else out there has had a similar problem, any ideas would be helpful, but yes the engine must be remove from the car for me to even attempt to try and remove it. amnit:
