If you can find a mold to use, you can squirt a little liquid steel on the hook-eye pocket and lay in your #2’s and close the mold until the steel is dry. Open, and carefully lift the hooks out and clean up any rough spots with a dremel tool, then cast. The liquid steel will be good for a couple hundred pours and will help reduce flashing around the eyes while still giving you a nice head. If the mold is meant for the heavier hooks simply add some of the steel to the hook channel where the shank lays too. If there is some interference from the #2 when the mold is closed, set it on a solid flat surface and give the top half of the mold a snap or two with a hammer. The aluminum will take on the form of the smaller hook without harming anything.
The liquid steel can be routed out of the mold with a wire brush in the dremel tool and bring the mold right back to the original intended use.
