Next point of call IMHO is rip the rocker cover off and start having a gander...
If needs be, fire it up with the rocker cover off and see if you can see any issues... There's gotta be one cylinder doing it, it's definitely an inlet valve, if you can get enough reach, stick a screwdriver on the inlet runner and see if you can listen to which cylinder it is?
