The cylinder head for internal combustion engines is produced by pouring liquid cylinder head material, especially aluminum, into a cylinder head mold containing a mold core having stepped sections in the region of the valve seat ring and the valve guide. The valve seat rings and valve guides are produced from a conventional material based on steel or copper by pressing and sintering in such a way that they have an open pore volume of 5 to 15%, a valve seat and/or a valve guide are laid on the stepped sections of the mold core, whereafter liquid aluminum is poured into the preheated mold and the mold core is removed in the conventional way after the molten aluminum has solidified.
