I have a leak in the same spot. It's coming from the area where the oil pan meets the oil pump/front cover gasket, leading me to believe it's the gasket for the latter. Or maybe even the oil pan sealant gave up, because I also have high oil pressure. If your balance shafts have been deleted, check your oil filter housing for the enlarged relief hole. High pressures will kill gaskets in a hurry, anywhere they can.
PS. Post pics if you pin-effin'-point where yours is leaking, I haven't had a chance to tear into mine yet, and it wears on my sanity to consider everything it could be.
