Man, those are some nasty pics. I don't even see how a block can have any integrity at all after all the cylinders are cut out in that last pic. Man, that would suck.

Well, I think I had already made up my mind, that I would just bore to clean up...but you have put some more red flags up...

I know by taking .030 or .040 out, I should be fine by looking at just thickness numbers alone...But I'll take a closer look inside the water jackets and survey the damage before I take it to the machine shop. Would you recommend doing another sonic test after the boring is complete?

Thanks for all the words and pics, George.
