Are you sure that the spark plug wires were reinstalled in the correct order? That will certainly cause it to sound out of sync. Also, can you record it cranking so I can hear what you are referring to?
See the attached pic and confirm the spark plug wires are going from the correct point of the coil to the correct cylinder.
Let me know. Also, if you record it cranking, I can tell if the plug wires are the likely cause.
