NOW I HAVE FIVE BROKEN HEAD BOLTS THAT ARE BROKEN ABOUT
AN INCH BELOW THE BLOCK. I GOT OUT THE REST THAT WERENT
SEIZED UP AND NOW I CANT GET THE REST OF THEM TO TURN AT
ALL IVE TRIED EASY OUTS I HAVE TRIED LUBRICANTS BLASTERS
ANYTHING UNDER THE SUN AND WELDING ISNT AN OPTION
BECAUSE THEY ARE INSIDE THE BLOCK WITH NOTHING STICKING
OUT I REALLY REALLY NEED A GOOD IDEA HERE ANYTHING THROW
IT AT ME
You may be down to drill and tap as an only option my friend.
I would take it to a machinist and let them deal with it. A spark erosion tool might be the solution. https://www.youtube.com/watch? v=fxx5lIGesjg
WHAT KIND OF BIT WOULD BE THE BEST
IM NOT SURE WHAT A SPARK EROSION TOOL IS
Ask a machinist about that one as it is a highly specialized tool. Even drilling and tapping should be left to a good machinist because if you drill crooked you will ruin the block.
EVERY MACHINE SHOP I HAVE CALLED TELLS ME THAT THEY PROBABLY CANT GET THEM OUT I GUESS WE HAVE BAD MACHINISTS AROUND HERE
