k so im doing my head gasket and i took the head to the local car/machine shop for them to check it out the shaved a little off the head and i got it back. thats all good i put it back on hook everthing up and go to put the spark plugs back in number 2 3 and 4 go in fine i got to put the last one in and im screwing it down and i here this nasty griding noise then i realize ok its down nice and tight but yet it is about half an inch higher then the other three so i pull the plug out and it is curshed. there is no gap in the plug i look down in the hole and something is stuck down there and it apears to be actuly threaded in. would this be something the shop would have put down there for any reason. as you can figure iv tried everything to get it out and it won't budge. any idea i need to get this out asap. please anything thanks

well to determine the best way to extract something would be to know (or see *hint *hint) what exactly it is/looks like...
