What did it do to the head? A rocker ball can't get past the rings and it had to of smashed into the head for it to have busted the block...in which case the piston would be toast too...but you didn't mention any damage to the head or piston...,just the cylinders. :?:
Not saying it didn't happen I just find it odd no damage to the head or piston.

Well, I'm going back to my corner of this little shop, sit down on the stack of slicks, drink my coke, and STFU. I'm now convinced, That I'm wrong, And I apologize to all involved. I take it all back, except the part about running around madly, waving my arms. My wife says that's a regular occurence around here. SHE IS, the only person around these parts, who's never wrong. :lol: If y'all say, what I thought happened, didn't happen, that's good enough for me. Anyway, once again I apologize!

The ball was close to the valve opening but would not go thru. Soooo i don't know :!: :!:
