did I ruin my head

[jeepxj2007]

on my drivers side I broke the exhaust manifold bolt off on the top portion of the middle exhaust port. I drilled through it and tried getting it out with an easy out, when I did it made a crack run from the upper right part of the manifold mounting part of the head to the hole, I don't care if the manifold leaks, I just don't want it ruining my head because I just pretty much rebuilt everything, I drilled the whole bigger and the crack stops at the hole, I put a bolt through it with a nut on the back, it looks as if it would keep cracking that it would only break off the corner where the hole is, so basically it is traveling towards the ground and the front of the motor. Will it be okay?

it sounds to me like your going to be ok, but to be sure can you post a pic of the crack

here are a few pics...the first two are off the crack, the second picture where you can see a lot of the engine is just to show about what angle the crack travels, but it stops at the hole where the top bolt should go.

I am pretty sure if it was to crack more the top corner would break off where the bolt hole is...i just want to get a few opinions and make sure that it wont crack and ruin my head, I can live with the extra noise..just not a ruined motor

that looks pretty minor. i doubt it will crack further and i seriously doubt its going to leak.
