Yesterday I had broke a header bolt inside the head. I didn't have access to an easy out, so I decided to drill out the bolt and tap out the threads. It just so happen that the tap broke inside the head also. My question is. How should I get the tap out. Should I just try to break it with a center punch or drill it out just like a bolt. Also once it's out should I try tapping it out with the original 8mm or should I try something bigger?
