I've completely torn down the engine on my 1950 Chrysler Windsor Sedan, as the engine was seized when I bought it. I have yet to collect any precision measurements (I don't own any machinist's tools), but I did notice a few things as I disassembled the engine, and I'd like to know if any of you have any advice. Primarily concerning me right now is the valve train. While some of the valves slid right out of their guides after I had removed their springs and retainers, there were a few that were so stubborn, they required vice grips, penetrating oil, and nearly an hour of twisting and tugging to remove. What's odd, is that aside from the damage inflicted by my vice grips, I couldn't find any apparent deformities on the stubborn valves. I'm wondering at this point if there's any good way to determine if the problem was my valves, valve guides, or both. Additionally, after finding what's available on Vintage Power Wagons, I've been considering the possibility of installing modern valve seats and valves to allow for the use of unleaded fuel. I hope to one day drive this car daily, and don't want to deal with tracking down and adding a lead substitute at every fill-up. Does anyone here have experience in running these fatheads on unleaded? Do the original valves ruin themselves if you do? This is my first engine rebuild, and any advice on the subject is greatly appreciated.
