'70-71 Mopar 440-6 / Hemi Stocker oil pan & volume

What oil pans do the '70-71 A-C/S 426 Hemi and 440-6 cars use? I know the '70-71 OEM pan was a 6-qt (w/ filter?) model. Do Stock Eliminator cars use the repro pan like Mopar Performance and some other places sell? Are the baffles modified (extended or?) , or do the rules mandate using an unmodified pan? Since I use the MP repro pan w/ my 10-second street/strip Challenger, I'm curious if there are any typical mods done to improve oil control.

Also, with 5 qts in the pan and 1 in the filter, my OEM 440 dipstick shows "full" w/ my repro pan, so that's as much as I've ever run in it. However, I know people using this pan who run 6 + 1 in the filter. Does that raise the level in the pan enough to cause any windage issues, even w/ a louvered tray?

FWIW, the "5 + 1" approach showed steady oil pressure from 3500-7000 RPM on the dyno. Also, I haven't been aware of any pressure fluctuation issues on the track, either, but I still wanted to ask about running the extra quart.

Thanks!
