Just for variety, I have three pressure-fed three main bearing engines, these have a 1/8" spacer plate between block and crankcase which is slotted about 1" wide to clear the con rods. There might be some difference from the standard set-up, with oil exiting the centre main at about 50 psi. The plate at least partly shields the bores from excessive oiling, and I can't say I've ever had an issue; nor can I say what would happen if I opened up the slots as I've never had any reason to do so. It's a bit of a faff including the spacer in the build but it's quite do-able.
I only have one running two-bearing engine, and like Parazine I didn't see any special reason to leave the baffles out. They are split though so they can be fitted over the con rods. I'm not sure I'll bother with them at next rebuild.
