I noticed there's a pretty significant slope to the carburetor mounting face. Looking at my original one-barrel manifold, it has the same feature, maybe a bit less exaggerated. I don't know if that's by design or just loose design tolerances. And now that I see the picture up close, I see that I probably should go back and clean up that EGR gasket surface...IMG_3483.JPG
