SURFACE PLATE ADAPTER
Some cylinder heads, like small block Mopars, have the intake manifold bolt holes at a slight angle from the manifold flange. This makes it hard to mount on our surfacing machine milling plate because, when you tighten up the mounting studs against the plate, it wants to bend the stud. I took some 3/8” bar stock, drilled holes through it and then ground it into 10 degree wedges using my surface grinder. Now I install the wedges on the opposite side of the plate and it clamps down perfectly without bending the mounting studs.
