As far as the original question goes, a basic sump baffle as bigblockmopar posted will be fine. The problem with these pans is the relatively shallow sumps - and back wall is worse than front due to the clearance needed for the oilpump.
IMO a long baffle about 1/2 way up the sidewall can also help. These baffles won't trap the oil, but will redirect slosh and splash back into the sump.

Also when using a factory small block windage tray open a couple more louvers on it. That's an old tech bulletin tip and I had class racers tell me it makes a difference at high rpm.

The accussump brings its own quirks. I'm actually not using mine right now. Haven't for a while - although its ready if needed, but does not have differential fill vs empty arrangement. IMO that's important. The electric valve's big advantage is the pressure switch prioritizing the oil to go to the engine first. Tim added the pressure switch and that helped address what had been a problem.
