I saw an artical a while back on welding cast iron. I couldn't find it on a search of forums so if any one could help me out that would be great as I have a iron head I need to repair. I also played with the idea of welding up the open side of the chamber to make closed chamber heads out of my heads. They are an old set of stage IV heads that I have had for a while so there is no cash out lay and I have a friend with a engine shop. Juts a fun lets see what if project as I know that there is far better heads on the market.
