I use an 02 socket that has a hex head on the end and I have a big ass wrench that fits it perfect.
I can wedge the socket up there and the wrench just barely clears but its enough to break it loose and then thread it out by hand.
also spray any stubborn bolts down with PB Blaster.
That stuff kicks arse.
And I believe the CORRECT bolt is a 14mm 1.25 pitch.
Mt header bolts were studs with nuts from the factory and on the pass side the studs pulled out when I took the oem headers off so I replaced that side with stainless bolts.
