I changed the intake manifold because there was.

I changed the intake manifold because there was a little seepage to the outside on the front with the updated metal one. Everything went smooth. Simple job. When I tried to start the car it seemed like the engine was locked up. The crank turns by hand almost one revolution then stops. I have since removed both heads and the timing chains and the starter and it still will only turn one rev. The heads and pistons look perfect. Could something be in the oil pan? How would that be possible? I am out of options.

Most likely coolant in the cylinders. Remove the plugs and crank the motor.

Why did you do that? When you re assembled it, what was your findings. Most likely did not need to be removed.

The engine does not turn over even with the heads and timing chains off. One revolution and thats it. #4 piston stops about an inch before top dead. I thought that I might have dropped a bolt into the cylinder but thats not the case. It has to be something in the oil pan restricting the crank. Its the only thing I can think anyway.

When you tried to start after the original job, with the motor not turning and trying, I bet you bent a connecting rod. Drop the pan and take a look. Most likely will need removal of the motor and rebuild

What could have caused a rod to be bent? Not a little coolant in the cylinders. Could it?

Yep. Hydro static lock. Cannot compress a liquid without something giving way. In your case, it was a connecting rod.
