Idea resin bond sand

it may work if you can get it to release from the head, me I think I would make a silicon rubber mold and make wax ones and invest them, with the bolt bosses, you can't just mill the slots plus they wouldn't look the same.

From looking at them I would almost say that they were injection molded,

Fins are a pain in the butt to mold and cast and get them to come out right.

what ever way you go your going to need some good ones to make the molds off of.
