Just to give an update, I did replace the O-rings with new ones made from HNBR material for use with R-134 refrigerant. HNBR is designed to stand up to just about anything including solvents and fuel, its the same rubber material used to make timing belts. Both quick connect fittings are now tight and leak free. There were two O rings per connector and they required tremendous patience and a set of picks to replace. The rings used on the pressure line are slightly larger than the ones used on the return line. I also discovered a couple of broken vacuum boots that I will replace and a worn out gasket on the MAP sensor on top of the PCV valve cover. I changed out the contaminated oil and filter and cleaned up all of the vaccuum connections. I still have a strong fuelish/exhaust odor when I remove the valve cover cap and smell the oil. Hopefully the work I did will help keep the oil cleaner, as long as it doesn't get any worse than what it was before I'm not terribly concerned. Theres no way I am going to pull a head or have someone pull a head to work on the rings, unless they are physically broken. Most people i know who have attempted work involving the removal of the heads end up with worse problems than what they started with. I may purchase a leak down test kit to determine if any of the cylinders are leaking down excessively.
