I think Im gonna be sick. Just finished the assembly of my short block today and when I went to torque the first head I hear a snap . so I pull the head back off to find that the bolt hole where the head alignment dowel goes had a helicoil put in at one time and it had just pulled the whole thing out of the deck. Now I have a huge hole (1/2 or so) where I need 7/16 threads. Any ideas???
