I put cork on mine about 500 miles ago.
If you look, you'll see a somewhat mis-matched indentation on the lip of the pan where the end seals go.
I put a good size blob of permatex right there, a dab where the seal and rail gaskets overlap, and a dab where the timing cover to block gap is.
No leaks so far.
I did double torque the bolts after the initial sequence tightening- at about 100 miles I added a partial snugging turn.
