That tells me your cam timing is ok, and the engine should fire if it has spark and fuel. So, remove a spark plug, lay it on top of the engine where you can see the tip, and turn the engine over. Does it have a good hot spark? If it has fuel and a hot spark at the right time it will run. Get a timing light and check #1 spark plug timing using the timing marks. If the timing is even close, it will fire, so I'm guessing you are losing spark under compression, or the timing is way off, or you have the plug wires connected improperly.
