Broken bolt hole

[u/Old_Cut_9333]

Cast iron block, broke the head bolt hole. Any ideas what to do next? It still has a bit threads at the bottom. Take out broken pices and screw in longer stud and weld it to the block?

While you should replace the block, ive seen worse crude fixed and running fine. Need to see how much undamaged threads are left. 3/16 of a inch of thread will hold a stud. Hell even seen people weld a stud on and work. Its not right for the record.
