Default Rear Main Cap - leaking oil - please help

428 FE
Mains have been aligned bored
So the rear main cap sits lower than the oil pan rail
I think its leaking here
I have aviaid oil pan, windage tray and two Milodon oil pan composite gaskets

Oil leaking down the center of the block plate shield, sides clean
Flywheel clean
Rear main cap side rails sealed with black silicone
Rear seal is 6000 miles old
I checked it once before, looked good, I dont think its leaking

Any suggestions? An extra thin gasket to make flush with the rail? Maybe I should use the rubber and cork gaskets?
Thanks.
