Your configuration is different from mine. The depressed area with the three holes is the drainback. As
oil is expelled from the aft side of the rear main bearing, these holes allow it to drain back into the
oil pan. You want them as unobstructed as possible.
I would put the first gasket on (between block and windage tray) and get it stuck to the block. Then I would cut out the portion of the gasket that is over the drain back area. I would then put it all back together, smearin adhesive on the gasket surfaces.
On mine I also cut the part of the gasket that hangs over the rear main cap bolt recesses. This may not matter, but it can’t hurt anything.
Good luck.
