2002 Valve Cover Gasket Replacement - HELP!

2002 Valve Cover Gasket Replacement - HELP!
I'm in the process of trying to replace the passenger side valve cover gasket on my 2002 F150 w/5.4. My Haynes manual is a bit misleading, and I need some advice for those who have done this before.
I'm to the point where I have removed all the valve cover bolts, but cannot get the valve cover out due to interference by the wiring harnesses between the valve cover and the firewall. I've disconnected the harness from the fuel injectors, coils, A/C compressor and crank position sensor. Have also disconnected the big multi-pin plugs that are mounted to the firewall next to the battery. How do you get these harnesses out of the way so that the valve cover can be lifted directly off? Haynes says to disconnect the heater hose at the back of the engine, which may make a bit of extra room, but I don't see any way I can get back there with a pair of pliers to disconnect this.
I'm hoping to get this truck back on the road by end-of-day tomorrow.
Thanks!

This morning I was able to remove the valve cover after slipping the wiring harness down below the valve cover, along the firewall.
Now that I have the cover off, I think I've identified the problem area, but would love to have some reassurance. When I first noticed the oil leak, the oil seemed to be dripping from the bottom of the thermostat housing, down into the intake valley, then off the back of the motor, around to the starter area and onto my driveway.
Bottom of thermostat housing/intake valley:
With the valve cover removed, it appears that the gasket was leaking just behind the dab of RTV by the timing chain cover (assumption is based on the fact that the mating surface on the head is clean in this area)
Does it seem likely that oil would be pushed through this are with enough force to cause a significant leak? Is there any oil passage that would possibly be above this point on the motor?
