hey all got a tid bit of info for you. upon removal of spark plug, the threads break off in the head, use a 3/8 internal pipe wrench to remove said threads!
i wish i knew about it a few months back, a buddy just had it happen to him so i went to lowes and they showed me , cost around 5 dollars and works like a charm!
better than the strait flutted screw extractors ive read to use

hope this helps somebody
