Quick update. I created a post in the engine forum (gray ghost engine post). In case you've missed that discussion, long story short is that the cylinder heads from both engines are removed from their respective engines and are now sitting in a machine shop. The goal is to get one good head and then install that onto the block that is still in the truck. A full engine rebuild would have been the preferred choice, but I simply don't have the money to do it right now. If I can make this work well enough to drive around the neighborhood, I'll call it a win. Even if it burns some amount of oil. At least, then, I could enjoy the truck while saving up for the full rebuild. It's not the best outcome, but it's what I've got. On the bright side, I spent over an hour with the machinist yesterday. I learned a lot! I'm very comfortable that he is treating me fairly and he seems knowledgeable about his craft. I'll post more updates as things progress. I'm going to have plenty of questions as I attempt to reassemble everything into a working engine!!!
