I installed the EBS Racing oil baffle and replaced the oil pressure regulator spring/piston today. Took me about 3 hrs (took my time). Overall, very easy and a good afternoon project!
Here is the stock oil pan and baffle. The oil pan was very clean and didn't have any particles or sludge (a few small pieces of oil pan gasket material that came off when I removed the pan). Oil filter was completely clean too.
The one thing that I noticed about the stock baffle is that the rubber window shutter was kind of warped so it didn't lie flat along the baffle any longer. Not sure if this would have caused any issues but I expected the flaps to lie flat against the baffle windows to close them off completely.
The botton of the engine was very clean (much cleaner than I expected after 100,000 miles). The oil pickup screen was completely clear and clean.
Here is the EBS Racing baffle installed on the oil pan and ready for installation:
