Pour in with intake flange facing down and a plate bolted on it to keep the aluminum flush. Aluminum will get solid very quickly. You can warm the head up some before pouring the molten aluminum in.
It's tricky.....and there is zero working time there....
If you pour too much in you will have to use a die grinder to grind it back....
I have seen some furnace type cement used that held up very well but never knew what product that was or where to get it....
