Hotrods got the engine internals covered. The factory manual list compression at 130# per cylinder, so your in the ball park. Except for those two cylinders, probably the head gasket between them. When you check the tail pipe check the underneath the truck for oil. It's not in the water. I had a crack in the oil gallery above the cam, and the oil got into the water not the crankcase.
It's got to be someplace.
