Umm, well, in the picture I posted, you can see there is either what I would call a steam erosion trace or a crack just north of the valve between the water jacket and the combustion area. Several old salts here at work have looked at the gasket and cannot see that there was a problem.

I can say that the head bolts didn't seem equally tight. So, that may have been the start of it all.

I'm sure it's been asked before, so I'll search the threads for a reputable Indy in Phoenix.

Thanks!
Michael B.
