Ok, I went ahead and checked one intake manifold bolt right up front with a torque wrench, and it was showing at about 20 lb/ft. This page suggests 30 lbs/ft for a 350 with iron heads: Boxwrench: SB Chevy V8. Should I torque all the bolts to that?

I checked the and photographed the PCV, the hose as well as the general area for the spark plugs. Unfortunately, due to the camera I am using, I have to back off quite a bit in order for it to focus so I don't have pictures for all the spark plug holes. However, it does seem that there is oil right outside where the spark plugs go in on cylinders 6 and 8. I have not been able to verify it for 5 and 7 because there is too much in the way. However, 2,41 and 3 seem pretty dry on the outside.
