I think the silicone mold will be good for many repeats but I have not done this myself....although I consider doing so every year. I have some vague recollection when reading about it years back that the molds would last for 50 or so pours........but I am not certain.
You can buy blank aluminum molds (red top used to sell them) and attempt to machine your own head shape but that seems well beyond my ability.

"Dow Corning 3120 Red RTV works great. Go to their site to find a local retailer. 3120 is a high temp RTV silicone. I've poured hundreds of castings from one mold, Look to pay about $25 per lb."
