Like "882", there are more than one "624" (as others have already said). One is the "light" casting, the other, "heavy". Flow from either is not real good... But the heavy castings are pretty tough.

To identify, the "light" casting has scalloped areas along the lower edge where the bottom row of head bolts "live". The "heavy" casting will have no scallops, and probably a single "notch" with a long "straight edge" where the lower row of bolts are.

FWIW
