The usual method is to use an "easy-out" or similar screw extractor. These come in different sizes, usually in a kit with a wrench of some kind. To use these, you drill into the middle of the broken fastener and screw the easy out into the hole in a counter-clockwise direction. The easy out gets wider as it screws into the fastener and the friction eventually causes the damaged fastener to rotate in the same direction (ie. counter-clockwise and out). It usually helps to apply a little penetrating oil to the broken fastener, particularly if it's seized or rusted in place (quite often the reason the head broke off in the first place). Sometimes the original thread will need to be repaired with a helicoil or time-sert once the original fastener is removed.

Obviously, it's important to keep the drill bit straight. This is sometimes easier said than done.

Good luck.

I would remove the manifold center punch the exact center of broken bolt (stud) an if you have access to a drill press use that for a straighter hole ,then use your easy out,don't buy a cheap easy out as they are prone to breaking and then you have double trouble. The reason for removing the manifold is so if you drill through the bolt (and you will) then you have metal cuttings from the drilling in your intake maifold and it will be be hard to get all of them out.........
