Troublesome Oil Leak

I have a rebuilt 340 and went to do engine break-in and had a couple leaks that I can't quite solve. One appears to be coming from the rear of the engine around the distributor o-ring as well as the fuel pressure sending unit, and the other is coming from some mysterious location near the front. Valve cover gaskets are dry. When viewed from the front, the passenger side head has a little bit of oil near the bottom left corner of the head. I tried re-torquing the head studs on that side per Edelbrock's procedure listed in their instruction manual for the Magnum aluminum heads. I also noticed oil pressure was reading around 60 - 70 psi at 2500-3500RPM and thought that seemed a little high. Also worth noting that the oil level seemed high when I checked the dipstick - have a stock pan and put in 5 quarts with the new filter. Could either of those be a contributing factor? I can go out and get pics later but just wanted to pick your brains. Leak is substantial enough that both locations made little pools about as big as a sheet of printer paper under the car.
