Unless you have the proper equipment and a good blueprint/drawing to go by, I wouldn't try casting and machining a head unless you are really bored, have patience, and willing to accept defeat with trial and error. I spent over 35 years in the automotive industry, beginning in 1973 as a basic machinist learning the machine tool trade and ending in 2010 as a mechanical/manufacturing engineer. Machining is my forte, a CNC turning and milling specialist, as well as QC, and supervision. I can cut you a piece of steel, cast iron, or aluminum within 10 microns but when it comes to cutting wood, forget it -I couldn't cut a board straight no matter what. I had casting and forming classes in college, melting our own scrap aluminum, making our own sand molds, and pouring the molten aluminum. One of my projects was a Ford 9N-9425 Manifold -minus the cores -we didn't have that much technology in the lab. As an engineer for three different Tier 1 companies, I spent many days in plants, foundries, and supply chain customer's facilities helping solve problems and seeing and learning all aspects of manufacturing. I spent 2-1/2 years in the GM Casting and Forming Plant in Saginaw, MI with our cylinder liners being cast into lost foam molds. I did however have a guy in New York make me some cast iron pulleys for the original small 9N-10000-A generator a few years ago and he did a fabulous job. I supplied a broken original and the original drawing for him -SEE HERE:
