So I was tearing down the FL350 Engine I got with the Odyssey I am rebuilding. I took off the top of the Engine no problem and started removing the head studs. 6 out of 7, no problem, number 7 cracked below the plane. I tried penetrating fluid, using an easy out, and finally drilling out the remainder of the stud. I am pretty sure I have mucked this up beyond repair (or at least beyond my current capabilities). So now I am looking for a cylinder head casing to replace the one I screwed up. If anyone has one, please let me know. Thanks!!

Pictures please.
You may be able to just use a helicoil.
