For the SGE cylinder head core boxes: 'C' (S & T cores) and the 'B' (D, I, E, U, W, L, B cores) core box LOWER halves, add the 3.0mm or 6.0 mm diameters holes where specified, allowing some "freedom" to route/drill the angled holes where beneficial to tie into an already existing hole to avoid excess drill holes in the back side of the cavity insert. Relief holes on the back side must meet GM guide lines/specifications. Ref PR6335OY
