Mike, are you sure you have the camshaft correctly timed? It is essential to line up the dots on the timing gears precisely, when you put it back in. If you are certain about the cam timing, you need to check the tappets as Joe said. Once you have those points correct, you might try squirting a spoonful of fuel in through the spark plug hole and checking whether it starts and runs at least briefly.
If you can report back on the results of those items, we can run a diagnostic process if necessary.
