Recently changed the entire head and two pistons, along with the radiator. Started with an intake gasket leak. After replacing all parts, started the vehicle without covers and drive belt. The cylinders were lifting fine, and the vehicle ran for 10 seconds before we shut it down. Placed all covers back on, valve cover, intake front cover over timing chain. Reattached belt. Tried to start and it started to fire up then shut off and wouldn’t crank, began leaking oil down oil pan and exhaust manifold.

Wow, that's a good one. Let's attach a breaker bar at the front of the engine to see if it will turn over by hand. Did you hear a noise before the engine stopped? You may have a piston or rod that has come part which caused the engine damage and oil leaks. Let us know what happens and please upload pictures or videos of the problem.
