Port molding. 3D model of your porting work

I know one thing I over-ordered trying to cheap out on shipping I guess. Its not like you pour a port every month. Heck I couldn't tell you how many small block Mopar Edelbrock heads I've ported and never poured one but I will be hopefully this winter. I had several bottles get hard and I had to throw them out so that plan really worked. LOL
