Just wondering, whats behind the ex. manifold bolt holes in the head?
Say you were drilling the holes that hold the headers on. If you went too far, where would you end up? A coolant passage? Anything?? juuuust wondering...

I can only vouch for the 4 interier holes. The reason being, I spread the bolt pattern. Very confident inside hole location, outside of end ports, is also in coolant passage. It is close, but it APPEARS extreme outside holes, on either end, would not be in coolant passage, if drilled deeper.
