Speaking of windage tray mods, this one looks a bit strange. The tray part is welded to the rail part, but my oil pan has wide flat rail surfaces.
This sure looks like it's going to hit the gasket. I have a Superformance pan gasket on order.

So - should I trim the gasket so it abuts but does not overlap the protruding tray section? Use a thicker bead of RTV on the flat parts to build up thickness?
Find a narrower gasket? shruggy

Edited to add: I am never using Duplicolor rattle-can engine paint again. Only about 30-40 minutes of run time on this block. Yes, the surfaces were prepped according to instructions!
