Very common leak area among the many. Cork gaskets are my go to gaskets. I have best luck with them. It's the cheap, paper thin covers and the lack of proper number of fasteners that are the root cause. Make sure you have a high quality, newer gasket in place. I tack it to the cover and install clean and dry on the head. Make sure the flimsy gasket rails are as flat s possible. Hammer and dolly as necessary to get them flat. Use Moroso load spreaders if necessary and the leaks will go away. They don't look 100% stock but are better than an oil leak. I currently have 1 load spreader in that right rear lower location. It was the only way I could get that cover 100% dry. Good luck. Making a Pontiac V-8 leak free is quite an accomplishment. The "Harley of the V-8 engines". Lots of places for leaks.
