That's good to hear but I put the heads on the block and there's water jacket openings as clear as day with an E7. It's not much but its there. I cant see how it would not leak since there's no head surface to seal the gasket to the block.

Since Ford made this great idea you would think they would make some kind of expansion plug for the holes. I may make my own punch and die but Ford should have already done that.
