knock off air gap intake question

I had one when I first put my 5.2 together, wound up giving it to my brother because I thought something was wrong with it, but turned out to be head gaskets. Otherwise, the biggest thing I saw wrong with mine was less than perfect port measurements. They aligned well using the same method Mike did above, and there was more flash than I cared for, but nothing a couple kisses with a dremel or die grinder couldn't fix. Otherwise, there was nothing perceivably "wrong" with it.

I did wind up going with the Edelbrock though and have had no issues.
