Actually, I've never heard of the oil leaking inthat spot before, but it is sensible that a leak exists.
First off, I always get confused about "left" and "right" when dealing with an engine. I assume you are referring to the passenger side retaining screw.
Since this screw provides the double-duty of blocking the front of the passenger side lifter bank as well as clamping the cam plate to the block, it would seem reasonable, at first, that oil would not trickle from the screw head.
On thinking a bit longer, it becomes reasonable that a trickle is logical.
The cam plate's phillips screw has a split-lock washer on it. While technically splitlock washers are a "use once and throw away" item, I always reuse them. Not wise, but I use threadlock. In stock form, splitlock washers mean threadlocker is NOT required. If the threads are clean, it's very reasonable to expect a column of oil will spiral up the clearance in the threads between the screw and hole. Since the splitlock washer is slotted, it's very reasonable to EXPECT that oil will flow past the split after climbing the spiral.
Since the standard FE oil pump moves about 12 gallons of oil a minute at elevated RPMS, and HV pumps flow even more, the tablespoonish loss past the screw each high-revving minute may not be the finest example of "controlled leakage" in the world, but it doesn't seem to pose a performance threat at all.
Think of the seepage as additional lubrication of the timing chain to promote longer life if you require a comforting side to the logic.
Now I'm gonna have to try priming the pump with the timing cover off just to see what happens.
