What size is the bolt? Have you already given Irwin Bolt-Grip extractors a shot? They work 90+ percent of the time for me when there is room to properly hammer them onto the bolt. Only the ones 19mm (3/4") and smaller are easy to find in your parts store though. You can order larger from the Impact Performance Series, which I've personally yet to try.
From experience these work best early on before you further foul the head trying other methods.
A picture would've been useful in offering advise.
