Does anyone know where I can find a mold to pour jig heads? I have been looking all over but cant seem to find one

check out Bass Pro Shops' catalog or their website. They have many different types of molds. good luck!

Cabela's tackle craft catalog has jig molds.
If you are looking to pour round head steelhead you will have do slight modifications to the mold. The round head molds are designed for the aberdeen hooks which are to weak for steelhead. They discontinued the molds using the stronger hooks but they are easy to modify with a small file.
