The Air Gap is a bolt-on and go for most, others could find fault with it too.... but it’s a nice piece, the new Weiands need either cleaning up if using 318 heads, or opening up and tapering if using 340/360 heads, it’s just a matter of how much grinding you have to do to get it in shape. Crap shoot if the next one they sent would be any better. The Air Gap is well known to be a better intake ootb anyways. Nice port windows on this here AG ootb:
