This is why you should port match your intake (pics)
Please understand, the intent of this post was not to bash Edelbrock. I know in the casting process this sometimes happens. I believe this is from core shift...the mold for the manifold is made out of sand. They actually had this on How its Made (science channel) a few months back
interesting process. It just looks like my manifold slipped through the QC check. Im Just posting this so others know why you should take a look at your stuff before slapping parts together.
