If it would turn over problem free before you disassembled it, and now that it's been put back together, it won't.....my guess would be valve timing. It has to be right, in order for the piston to reach the top of it's stroke.
I thought it was the valves but I took the cylinder head back off to make sure and it's still not moving. It seems like the big end of the piston roof is stuck or jammed on the crankshaft inside the engine.
