My thanks to all for posting pictures and information. I have learned a lot. From looking at the -8 pics I think I see why ading a spacer between the baffle and the cooler helps. It gives the air more time to turn the corner past the cylinder into the lower part of the oil cooler.
Like I said earlier, I don't have cooling problems as long as I shift to a cruise climb in high ambient temps but the experimenter in me wants to try and lower temps a little. The wider cooler also makes sense.
