I think the 'accepted' method of installing casting plugs is by using a
suitable sized socket as a punch and bashing it in.
If you don't have a set of huge sockets, buzz out to the Cheapy Tool Mart
and get one that fits your plug.
I think you put form-a-gasket on the plugs too. Probably the blue stuff
would be fine.
