1. The T30 bolts on the valley pan nearly stripped. I noticed that grit and rust filled part of the head not allowing the T30 socket to be fully seated. I made sure to clean all the heads and pick out the grit.
2. You do not have to take off the oil filter housing from the valley pan (so I didn't need those O-rings.)
3. Clean as much as you can before removing the manifold as inevitably tiny amounts of grit/gasket pieces will fall into the intake. Since 6 or 7 of cylinders intake valves will be closed, you can suck the debris out with a shopvac
4. Quite a bit of oil comes out when the valley pan is removed, I'd say a good 1/2qt which drains down the engine. Anyway of purging this oil so it doesn't leak down the engine? I guess you can take out the oil filter and suck out some of the oil.
5. I found some RTV gasket material was lodged in one of the check valves! I do know the engine was rebuilt at ~12k from a dropped valve so I'm guessing this has been there ever since (now at 90k)
Still need to reassemble as I also found out the previous owner removed the intake manifold runner flaps! No wonder I don't have low RPM torque! I"m finding all sorts of hack jobs on this car but they are getting corrected...

As far as the oil seepage once the valley pan comes off, removing the oil filter which is obviously full of oil should greatly help with the oil spilling. I pulled out the saturated filter and put it into a plastic bag but still had to use a ton of shop towels to mop up the oil. Doing this job when the oil is stone cold should definitely help since most of the oil will be drained down to lower areas of the engine.
This job can be done without removing the oil filter housing but since the rubber gaskets under the housing tend to crack and leak over time I changed them out while I was in there.
