Ray,
The engine never had to be unstuck. It was only owned by my grandfather, who was a mechanic and machinist. Last thing he did before he died in 85 was rebuild the whole engine. After that, it has mostly sat indoors without running. It ran okay if a bit rough before breaking down the engine, but with a misfire. So I decided to break it down as much as possible without pulling the engine--that is a bit beyond my capabilities and facilities. When I pulled the valve cover the rocker arm was pretty much inundated with gunk. So I kept going and now I have the head, manifolds, radiator connections, and oil pan off and completely cleaned. I have a whole gasket set because they all look pretty rough to me and I think that forty years is long enough for them to last. I hit the top of the block and pistons with a grinder with wire brush, because they were seriously fouled. I will carefully look at the cylinder walls as Ed suggests and hope they are okay. One push rod is bent, but I think I see the way clear to remedying that.
