I also forgot to mention that the most durable casting material is baked sand. You don't have to pour right away and they only break down with heat and water. Anyone here know this process????? I only have book knowledge but I'm willing to learn all of this. Edy just found his old cracked Chevy/Lotus head and offered it to me for this project.
Thanks again guy's
