I second that. There's a guy over here who runs a small business 
specialising in removal of broken studs, etc. I decided not to give my 
200's head to a machine shop and also not to call this guy and attempted 
the removal myself. I broke an EezyOut in the head and wound up running 
through 2 titanium bits and finally had to overbore 2 or 3 holes in 
order to fit threaded inserts. Should've just paid the to come and 
remove the broken studs. :P
