have you already cut the tabs ? mine always have tabs that extend up over the china rails that need to be cut before the intake goes on . I do it with the heads on so it gets cut flush to the edge of the head .
Yeah. They are one side up, one side down. As you can see, tabs are wacked off after I set the heads on. I'm guessing the water passages are OK like this, but I just don't remember it before..
Other side is the same thing, of course blue is down on that side..
