Interesting stuff.

I once hesitantly used JBWeld on a set of iron heads. Didn't have any problems.

Were you able to do the work on the engine with it still in the car? I'd really hate to have to pull it again but I'm assuming that will be necessary. I'll call the shops that I posted links to tomorrow to see what they say.

I'd be very scared to address this crack with jb weld. Especially in my situation since the block is brand new. I want whoever works on it to give a professional diagnosis as to how the crack occured because I don't feel like I should have paid this much money for something brand new and broken.

Helicoil, are you located in california?

With a crack like mine (and I know it's hard to visualize without pics) does a crack like this happen on an iron block from overheating during usage. I know it can't possibly be from handling but maybe I'm wrong??
