When the vehicle is laying on its side the cylinders will fill with oil. Oil will also go out the exhaust and can transfer through the exhaust manifold into other cylinders. Oil can intrude from the valve cover cavity through valve seals and into the cylinders too. A person flips the vehicle back on its wheels and tries to crank the engine without removing the spark plugs. Since you can't compress a liquid something has to give. So if a cylinder is full of oil or even 3/4s full, and the piston is on the compression stroke or if the valves are shut, as the piston travels up forcing the fluid to the bottom of the head, the valves get held shut. Then the weakest link will be found. I'm not saying this is the problem with this engine. But, it ran fine before the roll over and didn't pop through the carb. So either some one jacked with the distributor/timing, or there are issues in the engine now.
