Bolt stuck in head!
I was installing S&P headers on my LS2 and on the very last bolt I snapped the head right off like an idiot. Now I know I need to drill this sucker out but will this cause any damage to the head? Like cracking? Is there any other way to get this thing out? Keep in mind there is no part of the bolt sticking out.

eh, this is no fun with the motor still in the car....
Be very careful and ceterpunch the center of that bolt, then start with a small bit and gradually increase the bit size until the bolt is paper thin(careful not to get into the threads) and take a pick and if the bolt still wont back out, carefully fold the metal from the bolt to the center of the hole. Remove with needle nose pliers.1970 RS/SS350 139K on the clock:

If you have a good welder handy, lay a washer with hole little bigger than the bolt, weld that to it,then take a larger nut (hole size) and weld that onto the washer and bolt, then slowly turn it out.
Or drill and tap or drill and pick out parts.
